I think Christie is starting to be a little toxic around the edges on his union stuff, too. He has guaranteed he won't run (I know, politics... )
It will be Romney, unless, as it is pretty much a guaranteed loss, they let a cultural wingnut go through the motions. Which would be Huckabee. The base won't back Mormon Romney, they think Mormon Glenn Beck is okay, but Mormon Romney is in a cult
It's like they lined every potential GOP Pres candidate up, asked who wanted to run against Obama, and every one of them is taking a step back.
Will be an interesting Iowa. Romney is skipping Iowa, I'll say.
