Update: An analysis using more recent polls can be found here.
There are three new state head-to-head polls in the Obama—Romney match up since my previous analysis. All three states are important.
The Florida poll offers Obama a +8% edge over Romney. In Missouri, Obama and Romney are tied at 45%, and in Ohio Obama leads Romney by +7%.
| start | end | sample | % | % | % | |||
|---|---|---|---|---|---|---|---|---|
| st | poll | date | date | size | MOE | O | R | diff |
| FL | Marist | 25-Jan | 27-Jan | 2795 | 1.9 | 49 | 41 | O+8 |
| MO | PPP | 27-Jan | 29-Jan | 582 | 4.1 | 45 | 45 | tie |
| OH | PPP | 28-Jan | 29-Jan | 820 | 3.4 | 49 | 42 | O+7 |
All three polls reflect improvements over the previous poll in each state for Obama. It’s hard to tell if the improvements are a bump from Obama’s State of the Union address, a genuine lasting shift in public opinion, or whether voters are simply tiring of the Republican brawl.
After 100,000 simulated elections, Obama wins 99,439 times and Romney wins 561 times (including the 30 ties).
Obama would have a 99.4% probability of winning an election held now, an improvement over his 95.1% probability in the previous analysis.
| Obama | Romney |
| 99.4% probability of winning | 0.6% probability of winning |
| Mean of 332 electoral votes | Mean of 206 electoral votes |
