Rep. Jay Inslee (D-WA-01) held a town-hall meeting in the North Kitsap High School in Poulsbo earlier today. Kos diarist Pen gives a brief write-up:

The usual suspects were there with their “keep the feds out of my healthcare” signs and their baby killer signs. They were perhaps 25% of a large crowd that filled North Kitsaps auditorium full.

I was immediately handed a flier about ‘Death Panels”. I took it, perused it, then said to the woman handing them out: “So you really believe there are death panels?”

“Not yet,” she told me, “But there will be.”

“Oh, there ARE death panels right now, “I assured her, ” and since Obamas been president, the health insurance industry has presided over the deaths of 18,000 Americans.”

I handed her flier back and didn’t stick around to listen to her blathering as I walked away. I had seen the fear in her eyes when I brought up the REAL death panels going on today. It’s the talking point that literally destroys the right wings platform.

Read the whole thing.

Tomorrow Inslee holds another town-hall meeting at the Woodway High School in Edmonds from 1:30 p.m. to 3:00 p.m. Attendees are asked to RSVP by email at inslee.rsvp@mail.house.gov or by phone at 206-361-0233.

Today’s release of R-71 data has the total signatures examined at 117,069 (85.0% of the total). There have been 13,815 invalid signatures found, for an uncorrected rejection rate of 11.80%.

The invalid signatures include 11,178 that are not found in the voting rolls, 1,477 duplicates, and 1,160 that did not match the signature on file. There are 56 pending signatures. With 1,477 duplicates, we expect a duplication rate of about 1.82% for the petition.

The V₂ estimator gives the projected number of valid signatures as 121,129, a surplus of 552 signatures over the 120,577 needed to qualify for the ballot. The overall rejection rate for the total petition is now expected to be 12.03%.

A few more details can be found after the fold.

I wasn’t able to post these results yesterday, but today’s batch of R-71 data has been released. The number of signatures examined is now 110,288, (about 80.1% of the total signatures). There have been 12,983 invalid signatures found, for an uncorrected rejection rate of 11.77%.

The invalid signatures include 10,580 that are not found in the voting rolls, 1,314 duplicates, and 1,089 that did not match the signature on file. There are also 44 signatures “pending” that I am simply ignoring.

Great big caveat: A new third-stage check is now being conducted using the most current voter database on signatures not found in the older database. They have made it through volume 220 of the 510 completed volumes. This means that some of the 10,580 “not found” signatures will be found in the next few days.

The 1,314 duplicate signatures suggest a duplication rate of about 1.82% for the total petition.

Using the V₂ estimator, and ignoring the third-stage check, the number of valid signatures is projected to be 121,070, giving 493 signatures over the 120,577 needed to qualify for the ballot. The overall rejection rate should end up at 12.07%. Of course that third stage check will likely add another 500 valid signatures to the total, making qualification highly likely and the rejection rate lower.

Here is a crude history of the projected totals since August 11th. The vertical bars give 95% confidence intervals for the projected number of signatures. The red line shows the minimum number of signatures required to qualify for the ballot.

For some unexplained reason, the rejection rates were increasing through the 20th (leading to a decreased projected number of signatures). The third-stage checking started on the 20th, and I would have expected to see a decreasing rejection rate from that, leading to in increase in the number of valid signatures projected for the petition. Instead we see a flat line for the past three analyses. Perhaps an increasing rejection rate is being canceled by the third-phase check. Who knows.

Whatever the reason, if there are no last minute surprises left to perturb the pattern, R-71 will qualify for the fall ballot.

Please join us tonight for some politics under the influence at the Seattle chapter of Drinking Liberally. The festivities take place at the Montlake Ale House, 2307 24th Avenue E. beginning at 8:00 pm.

Perhaps tonight we can all bring our bound and gold-foil bordered copies of “Your Life, Your Choices: Planning for Future Medical Decisions” and group-plan our grizzly Jonestown-style mass suicides for the next time one of us gets depressed or an ingrown toenail.

(There are more media clips from the past week in politics posted at Hominid Views.)

A variant on Chris Rock’s “Another kid?” routine started playing in my head as I read David Ammon’s post at the SoS blog last night…

“Another change?”

“ANOTHER CHANGE???”

“Get the fuck outta here!”

(* Sigh *)

Look…it really isn’t about the roller coaster ride, where R-71 was losing and then winning and then losing and now winning again. It’s that I thought the Secretary of State’s office understood after the first time we went through this that we wanted real numbers of rejected signatures; not the number of signatures awaiting another check.

In other words, I didn’t simply want a pile of numbers to spin, fold and mutilate for my own amusement. I wanted numbers that had some valid analytical utility. And that means well-defined numbers. Numbers that, when attached to the label “Rejected: Registration Not Found”, gave the number in this category that were…well, actually rejected. That’s not what we got.

Okay…so how do things stand now, with some unknown number of signatures being shuffled from the reject pile to the accept pile? (See this and this for an update; something over 35% of the third-phase checks have been completed, based on progress made through yesterday.)

Today’s batch of R-71 “data” have the total examined signatures at 97,287 (about 70.7%). There have been 11,315 invalid signatures found, for a cumulative rejection rate (uncorrected for the final duplicate rate) of 11.63%.

The invalid signatures include 9,347 that are not found in the voting rolls in at least two check phases, and an unknown number who have made it through a third and presumably final check. There were 1,021 duplicate (or triplicate) signatures found, and 947 signatures that did not match the signature on file. There are also 52 “pending” signatures awaiting signature cards—I ignore these for now.

The 1,021 suggest a duplication rate for the entire petition of 1.78%, down from 1.90% yesterday.

If the numbers were final, we could use the V₂ estimator to project the number of valid signatures for the final petition and learn that there should be about 122,642. This gives a 2,065 signature margin over the 120,577 needed to qualify for the ballot. The overall rejection rate is down to about 10.93%. Yesterday this figure was 12.47%, but the phase 3 checks have returned formerly rejected signatures to the accept pile.

A Monte Carlo analysis of 100,000 simulated petitions, using the rates we have now, give the measure a 99.11% probability of qualifying for the ballot. Quite a change from yesterday.

Here is our graph showing the results from each data release for the last two weeks:

I am inclined to think this is the worst case scenario for R-71 proponents. That is, as the third-phase check is completed, the measure will gain on the margin of votes needed for qualification.

There is one other twist. Apparently there is some evidence that 7% to 15% of accepted signatures belong in the reject pile. I haven’t tracked down the details, and I have no idea what the SoS office intends to do about this. But, I’m sure the lawyers have their ears perked up! Way, way up.

Today’s R-71 data have been release by the Secretary of State’s office.

The total signatures examined has reached 88,191, which is 64.1% of the total petition. To date there have been 10,510 invalid signatures found, for an apparent rejection rate of 11.92%. This rate underestimates the rejection rate for the entire petition because it doesn’t account for the increasing rate of duplicates found as more signatures are examined.

The invalid signatures include 8,822 that were not found in the voting rolls, 867 duplicate signatures, and 821 that did not match the signature on file. There are also 44 signatures “pending” that I’ve ignored. The 867 duplicate signatures found thus far, gives a projected total duplication rate of about 1.90% for the petition.

Using the V₂ estimator, the number of valid signatures on the petition is projected to be 120,519 leaving a shortfall of 58 signatures from the 120,577 needed to qualify for the ballot. This projection assumes that the signatures examined so far reflect a random sample of all signatures on the petition. As I discussed yesterday, this isn’t the case. In the last several days, there appear to be an unexplained, systematic increase in the rate at which signers are not found in the voting rolls.

If we correct the apparent rejection rate of 11.92% for duplicate signatures, the total rejection rate for the petition should be about 12.47%.

The extent of uncertainty in the outcome of R-71 can be seen from the results of a Monte Carlo analysis of 100,000 simulated petitions using the rates observed through today. The red bars show the mass of failed petitions and the green bars show the mass of petitions that made the ballot:

In the simulations, the petition qualified 41,520 times and failed 58,480 times, suggesting that, if today’s rates hold, R-71 would have a 41.52% chance of qualifying for the ballot. But, as we have seen for several days, the rejection rates aren’t holding—they have systematically increased.

Finally, here is the big picture over the last couple of weeks. The blue symbols are projected median numbers of valid signatures for the petition and 95% confidence intervals. The red line is the number of signatures needed to qualify for the ballot.

If the rejection rates were constant over time, the blue line would be mostly straight (bouncing around a little). What we actually see is a decline in the projected signatures suggesting the rejection rates are increasing.

Why are the error rates increasing with time? It is hard to know. Yesterday I mentioned the possibility that there could be temporal correlation, so that signatures collected later are being examined later. Dave Ammons (communications director for Secretary of State) suggests it isn’t so. I’m not completely convinced.

Whatever the reason, R-71 has now made the transition from qualifying to failing. Sure…it’s just barely failing, but should the rejection-rate trend continue, it will soon transition to a “safe fail”.

At least until the rate trends reverse….

Update: And then there is this. A substantial number of “not found” signatures are now being located in a more current voter roll. This third phase check has upped the uncertainty….

Yesterday I took a break from my all-too-frequent analyses of the R-71 signature counts. I didn’t even look at the numbers until this morning. When I did look, a Spock-esque twitch afflicted my left eyebrow. “Curious”, I though. “But maybe it’s just a one-time fluke….”

The analysis of yesterday’s data showed the probability of NOT making the ballet increased from a nearly impossible 0.04% to an almost-interesting 0.91%. In fact, this slow increase in the probability of not qualifying has continued a trend begun after 13 August.

Well, if you like that result, hold onto your sou’wester, because today’s result will blow you away. I’ll present the results in three parts. First, the basic results for today, then we’ll explore the trends in the daily data dumps. Finally (and below the fold) we’ll look at the micro-level volume data to divine what this trend suggests.

Today’s R-71 data release has the signature count up to 79,195, (about 57.5% of the total). There have been 9,208 invalid signatures found, for a cumulative crude (non-duplicate-corrected) rejection rate of 11.63%.

The invalid signatures include 7,805 that were not found in the voting rolls, 703 duplicate signatures, and 700 signatures that mismatched the signature on file. There are also 38 signatures “pending”; I’ve ignored them in the analyses. The 703 duplicate signatures suggest a final duplication rate of about 1.90% for the petition. This continues the trend we’ve seen this week of the projected duplicate rate growing faster than the mathematical predictions under the assumption of random sampling.

Using the V₂ estimator, the number of valid signatures is now expected to be 120,777 leaving a thin surplus of only 200 signatures over the 120,577 needed to qualify for the ballot. From the cumulative data to date, the overall rejection rate is projected to be 12.28%.

A Monte Carlo analyses consisting of 100,000 simulated petition samples suggests that the measure has an 80.48% probability of qualifying for the ballot, assuming the only “error” is statistical sampling error.

Here is the distribution of valid signatures relative to the number required to qualify.

The red bars on the left show the times R-71 failed to qualify among the 100,000 simulations; green bars show the counts of signatures in which the measure qualified. Compare this to the results from just two days ago. Quite a difference!

Let’s examine the history since the SoS office started releasing accurate data a week and a half ago:

The red line shows the number of signatures needed to qualify, and the blue symbols show the daily projections of valid signatures, surrounded by 95% confidence intervals.

Clearly, since the 13th of August, the projected number of signatures has declined–and, as of today, declined more than we could expect by chance alone. Something is going on.

Tomorrow will be interesting…if the trend continues, success of the measure may dip below a probability of 50%.

The analyses I’ve done here are based on two assumptions: (1) that the signatures evaluated so far are just like signatures that remain to be evaluated, and (2) that the signature validation process is “stable” (the people validating signatures are not changing their standards over time). Today we see some pretty good evidence that one (or both) of these assumptions is (are) violated.

The supporters of R-71 will, no doubt, focus on the second assumption. If the measure fails, Secretary of State Sam Reed will likely take much abuse from fringe homophobes for “personally pushing a homosexual agenda.” To me, the simplest explanation is that the volumes being examined in serial order are chronologically correlated with the signature collection order. ( I don’t know if this is true; but, I cannot rule it out either.)

My thinking is that later-collected signatures (and therefore, later volumes) should have a higher duplication rate, just because there is an increasing chance with time early signers forgot whether or not they signed earlier. Additionally, with the last push of getting as many signatures as possible with an approaching deadline, it seems plausible that errors would increase. I’m thinking errors like collecting more out-of-state signatures, underage signatures, and signatures from people not active on the voter rolls.

Below the fold, I examine the fine-level data to see just what types of errors are increasing as the process proceeds. If you are still interested, click through…

Not in Seattle? The Drinking Liberally web site has dates and times for 335 other chapters of Drinking Liberally for you to shoot for.

Today’s release of R-71 data has the process nearly half-complete. Now 65,531, (47.6%) signatures have been examined in completed volumes. There have been 7,201 invalid signatures found, for an uncorrected rejection rate of 10.99%.

The invalid signatures include 6,165 that were not found in the voting rolls, 470 duplicates, and 566 that did not match the signature on file. There are also 24 pending signatures that I’ve not counted either way.

The 470 duplicates suggest that the overall rate of duplicate signatures for the petition will be about 1.84%. This is slightly higher than what we saw last week, from Tuesday through Friday, 1.62%, 1.74%, 1.73%, and 1.69% respectively.

Using the V₂ estimator, the number of valid signatures is expected to be 121,475 exceeding by 898 the 120,577 needed to qualify for the ballot. The overall (i.e. duplicate-corrected) rejection rate is about 11.78%. (Last week we saw 11.61%, 11.53%, 11.54%, 11,65%.)

A Monte Carlo analysis of 100,000 simulated petitions gives this distribution of projected valid signatures for the petition:

In only 34 of the 100,000 simulations did the measure fail to qualify for the ballot (those red bars on the left). The median number of signatures was 121,478 with a 95% confidence interval between 120,951 and 122,003.

As we saw last week…the measure has almost no chance of being rejected.

After the fold, I provide a rather dry analysis by small batches of signature pages for the R-71 obsessives and stats wonks….

CBS News examines the similarities and differences among the five different health insurance reform drafts in Congress:

[youtube]http://www.youtube.com/watch?v=irwmdDMZVP0[/youtube]

Now examine this mini-debate between Sen. Orrin Hatch (R-UT) and Sen. Arlen Specter (D-PA):

[youtube]http://www.youtube.com/watch?v=31-1SFncpIw&feature=player_profilepage[/youtube]

This is remarkable. First, Hatch refuses to take sides in the “Obama Death Panel” canard! Hatch then lets loose with a series of blatant lies (“government take-over”, “cut medicare”, “eight in ten of Americans really want their health insurance coverage and don’t want to lose it”, “nameless, faceless bureaucrats setting healthcare”, “single payer”, “government plan”).

Much of what Hatch is saying isn’t simply “alternative interpretations” of facts. They are fabrications that are so discordant with the actual provisions in the drafts that this can only be intentional deceit.

This is what Republicans are reduced to? Putting their senior statesmen on mainstream TV to tell barefaced lies to Americans? I mean, there is a deep tradition of politicians “spinning” facts to their cause. But discarding facts altogether? We tolerate unashamed lying from pundits and political operatives…but a U.S. Senator?

Or perhaps Republicans have become so enmeshed in their lies that they no longer recognize objective truth. This goes beyond deplorable; now it’s just pitiable.

(And there are some sixty other clips from the past week in politics posted at Hominid Views.)

A new batch of signature data for Referendum 71 has been released. The number of signatures examined is 58,493 which is 42.5% of the total signatures submitted. To date, 6,348 invalid signatures have been found, giving a raw rejection rate (uncorrected for duplicates) of 10.85%.

The invalid signatures include 5,502 that were not found in the voting rolls, 345 duplicates, and 501 that did not match the signature on file. There are also 30 “pending” signatures at various states of processing for a missing or illegible signature cards. I don’t count these among the invalid signatures.

With 345 duplicate signatures found so far, we can anticipate a final duplication rate of about 1.69%.

The V₂ estimator projects the number of valid signatures to be 121,648 giving an excess of 1,071 signatures over the 120,577 needed for the referendum to qualify for the ballot. The projected (duplicate-corrected) rejection rate is 11.65%.

A Monte Carlo analysis consisting of 10,000 simulated samples give a 95% confidence interval for valid signatures of from 121,175 to 122,415, well above the magic number. Here is the distribution of valid signatures:

There are a few “losses” in red on the left, but the overwhelming majority of outcomes in green have the referendum qualifying. In fact, the referendum failed to make the ballot in only 11 of the 10,000 simulations.

With the results to date, it is pretty clear that, come fall, we will be voting to accept or reject the “Everything but Marriage” law.

Since the Secretary of State’s office started releasing final numbers this week, it has become clear that R-71 is headed for the ballot. Short of some scandalous revelation—you know, like finding out that the numbers being released are not the final numbers—the measure should make the ballot using standard statistical inference.

(I kid the SoS with that “scandalous revelation” quip. In fact, they have done a remarkable job turning last week’s data disaster around. The data are now provided in excruciating detail and they have carefully described the meanings behind the numbers, both on the official release page and on their blog. David Ammons has been kept busy answering questions in both blog posts and the comment threads. And now Elections Director Nick Handy has a nifty R-71 FAQ.)

Back to the projections. One point that has repeatedly come up in the comment threads is that the signatures sampled so far may not reflect a random sample of all signatures. Thus, the statistical inference may be wrong.

The point is valid because the statistical methods do assume that the sampled signatures approximate a random sample. One can imagine scenarios where the error rate uncovered would change systematically with time. For example, if petition sheets were checked in chronological order of collection, the duplication rate might increase if early signers forgot they already signed, or if the pace and sloppiness of collection increased toward the end.

For R-71, we don’t know that the petition sheets are being examined in anything approaching a chronological order. The SoS FAQ states:

Signature petitions are randomly bound in volumes of 15 petition sheets per volume.

Rather than speculate on the systematic error, let’s examine some real data. The SoS office releases data that give the numbers of signatures checked and errors for each bound volume in the approximate chronological order of signature verification. As of yesterday, there were 209 completed volumes covering 35% of the total petition.

After the fold, I give a brief section on analytical details, and then show graphs of the trends over time in error rates and projected numbers of valid signatures. But first, I give an update on today’s data release.
