It's because of his record. He's a lousy candidate. If he turns out to be a liar, he could cripple the GOP. And "But, but, but.. He's better than Obama!" won't make a bit of difference.. America cast the GOP out in 06 and 08.. They got another chance in 10.. And they're better not blow it or they might get thrown out again. There was a time when the GOP was locked out of power for nearly half a century.. Is that what you want to return to? The party of dogs drooling on the butcher's shop window?
