Ann Coulter says that if we don’t run Chris Christie for President, then Romney will win the nomination and we’ll lose in 2012. I think she's hinting that she'll endorse him again as she endorsed Mitt in the 2008 elections.
Why do I think that?
Consider this statement when she endorsed Mitt in 2008 in the article I linked above:
"I've been casually taking swipes at Mitt Romney for the past year based on the assumption that, in the end, Republicans would choose him as our nominee. My thinking was that Romney would be our nominee because he is manifestly the best candidate."
Once again, she's taking a swipe at Romney as she did in the last Presidential election. I think she's trying to make a hint to conservatives and Republicans to endorse Mitt again this year.
Everyone knows that Chris Christie will not run for President in 2012 and as a result, she cannot be serious about endorsing Chris. Those who know her that her form of endorsement is through sarcasm and knock downs towards people she admires.
