Not that it would actually happen, but you think that a good number of conservatives wouldn’t jump at the chance to vote for Jeb Bush instead of Newt Gingrich? Not that Jeb is a great conservative, but Newt has a lot of baggage that people are overlooking because they really don’t want Romney.
If Newt won Florida and the GOP-e put Jeb in the race then enough people would move to him that it would be impossible for Newt to get the nom.
Perhaps Newt really is just waiting for Mitt’s point of no return....then BOOM! up pops NewtZilla :-)
Remember, this is the guy that brought in a Repub majority after 40yrs... and did lots of other stuff considered impossible until he did it.
