I'm hearing McCain is winning Greenville, which is very bad news for Huck. This is supposed to be his "Upcountry" base.
Regardless of who wins, there are still many questions:
Where do we go from here? (Based on the exit polling, it seems Huckabee can't win without Evangelicals -- and John McCain can't win without independents voting for him.)
As Bill Kristol just pointed out, one thing seems to have come out of this: Barring a brokered convention, Fred Thompson's presidential chances seem to now be over.
