40.4% Newt GingrichThe remaining 1.8% went to insignificant candidates. It is a very clear win for Gingrich, as strong as Romney's win in NH, but unlike Santorum's tiny lead in Iowa.
27.8% Mitt Romney
17.0% Rick Santorum
13.0% Ron Paul
I would not be surprised if Santorum was the next to drop out. It will be interesting to see if he endorses either of the front-runners when he withdraws.
