It's looking like Newt Gingrich (32%) + Rick Perot (13%) = 1% shy of Mitt Romney's 46%.
The question to me is whether Santorum's votes would split or go one way over the other.

Santorum’s votes would likely mostly go to Gingrich, but some would go to Romney, and don’t forget that some % of Santorum’s supporters would just stay home and not vote.
