Walker's campaign reminds me very much of Governor Tim Pawlenty's run last cycle. Good ideas, too Midwestern in demeanor, lost ground, bet the ranch on Iowa, ran out of money. Too bad. There were quite a few candidates with less chops than Governor Walker.
Interesting. I somewhat expected to see some of this after the first poll after the last debate was released. It's expensive and tolling emotionally to keep a campaign going when you are at the point that you know you can't win anymore.
