First Governor Gregoire and now Rick Larsen have endorsed Suzan DelBene. I’m not sure how much endorsements matter, but these are good ones to have. Her campaign also has raised the most money.
So it seems like the establishment support is coalescing around her. I don’t know if there’s anything other than money that makes her more establishment than Ruderman etc. She’s a fine candidate, and was willing to take on Reichert in a year that was going to be tough for Democrats. If Democrats want to give her another shot, that’s cool. But Ruderman stepped aside in 1998 to clear the field for Jay Inslee, and then actually won an election for legislature.
The main thing seems to be that she can (and has shown she’s willing to) self finance. If she needs the money, the Democrats won’t have to bail her out when Karl Rove spends literally infinity corporate dollars in the district.
