COLUMBIA, SC.---Texas Gov. Rick Perry is dropping his White House bid on Thursday morning in advance of the Saturday South Carolina primay--and the final debate in the Palmetto State, 8 p.m. est on CNN.

*Turns out Rick Santorum won the Iowa caucus, by 34 votes according to a canvas. Would have meant more if on election night Mitt Romney was not deemed the winner by eight votes.

*Newt Gingrich is being thrown a curve ball: ABC's Nightline at 11:30 p.m. est is going to broadcast an interview tonight with Gingrich's second wife. Marianne Gingrich tells ABC's Rhonda Schwartz and Brian Ross "Gingrich lacks the moral character to serve as President, his second ex-wife Marianne told ABC News, saying his campaign positions on the sanctity of marriage and the importance of family values do not square with what she saw during their 18 years of marriage."
