I don't think Chris Christie has a snowball's chance in hades of becoming the GOP nominee. If he does, I think it's about 85% certain that he'll be trounced in the general election. So far, the idea that he's the Republican frontrunner relies on a couple of very early polls and a narrative that's been a staple of the mainstream media. Democrats (and establishment Republicans) are quick to tell us that "he's the only man who can beat Hillary."
