And Ron Paul is still not invited according to WorldNetDaily:

Contrary to earlier reports, the Fox News Channel is hosting a Republican presidential candidate forum in New Hampshire, and, so far, Rep. Ron Paul has not been invited.
WND previously reported the event was canceled three weeks ago, but New Hampshire Republican Party Chairman Fergus Cullen confirmed today the forum is scheduled for Jan. 6.
The New Hampshire GOP is co-sponsoring the event, to be held at St. Anselm College in Goffstown, N.H., just two days before the crucial primary.
Candidates who have received invitations are former New York City Mayor Rudy Giuliani, former Arkansas Gov. Mike Huckabee, Arizona Sen. John McCain, former Massachusetts Gov. Mitt Romney and former Tennessee Sen. Fred Thompson.

I wish they would make up their mind since all this back and forth is confusing to this poor blogger and to the many Paulians who have to plan their boycott of Fox News.
