  I think ulysse is saying that Santorum doesn't have to bow out if his supporters vote strategically in this winner take all contest. Santorum doesn't gain any delegates in a winner take all that almost certainly will go to either Gingrich or Romney. I makes sense to vote for the remaining conservative who can win: Newt. If every one of his supporters goes to the polls and votes, it could easily push Gingrich over the top.
