Photograph: John W Adkisson/Getty Images 9.28pm: On Fox News, Karl Rove is talking down the scale and meaning of Gingrich's victory. There is something to be said for the end of the "South Carolina always backs the eventual winner" line that we've had repeated forever. It is based, as a statistician would say, on a very small data set: 1980, 1988, 1996, 2000 and 2008. That's not exactly the Oracle of Delphi. 9.13pm: Two-thirds of the precincts are in, and Gingrich has 41% with Romney trailing at 26%. On Fox News, campaign correspondent Carl Cameron says even the Gingrich campaign has been surprised by the size of his victory. Gingrich, according to the exit polls, won every category, including married women, which is quite something, considering the Marianne Gingrich interview on Thursday. It looks like Gingrich is having trouble getting into his own victory party, it's so crowded.
