When he hops over to Iowa, they'll expect him to denounce sharia law, make jokes about Obama's Kenyan birth, throw himself wholeheartedly into the culture wars, pretend that global warming is a liberal conspiracy, and make dire remarks about the specter of socialism taking over America. In other words, he'll have to act like a public clown, and if he doesn't do it, he'll lose.
So it's pretty much a no-win scenario for him. If he's smart, he'll wait for 2016 and hope that the Republican Party has come to its senses by then.
