What's the Deal With Dino Rossi?

In all seriousness, how many times does this guy need to lose close, winnable races in Washington State before the WA GOP stops nominating him?

They've got several congressmen, a couple of downballot statewide officeholders, and there's got to be someone recruitable among the ranks of Microsoft/Amazon/Starbucks executives. Right?
