In order for this to hurt Romney, he would have to drop below 5%, So hold your celebration for the moment.
Romney also has a few sleeper states running that will offset any losses here, like they did last weekend.
It looks like Romney will break even, and also the heavy Romney precincts have not reported yet. The rural, less populated areas are always the first in. The high populated areas that favor Romney and Gingrich, will not be finished counting until later.
Cautious optimism this evening, though. I'm keeping an eye on Jefferson, Tuscaloosa, Bibb, Madison, and Limestone counties in AL.
