I'm not sure how this is going to come out. I'm thinking that it's going to be close. Looking at RCP, I doubt that Romney is going to get as high as 41%, Santorum will get as high as 13%, and Paul (remember this is a closed primary) as high as 10+%. Will the differences be enough to put Newt over the top, though? I dunno.
I gotta say, though, that...
1) after all of the money Romney has spent,
2) after all of the nasty ads by Romney,
3) after a mediocre performance by Newt in the debates (he merely did OK, hitting singles instead of Grand Slams),
4) With all of the media pulling for Romney
5) And after every single poll projects a blowout for Romney
....Anything beyond a huge (15+%) win for Romney is an effective loss. He shot his bolt to get FL, but there's still 46 (53? lol! ) states left.
