Another Surprise for Republicans: Newt Gingrich

With Herman Cain out and only one month until real Republican voters go to the Iowa caucuses, the Des Moines Register's latest Iowa Poll shows the race for the presidential nomination is anything but settled. Newt Gingrich is leading with 25 percent, Ron Paul is second and Mitt Romney has dropped to third with only a month to go. Has Gingrich peaked like so many others, or is this growing momentum, despite a campaign plagued with debt, staff turnover and a lack of discipline? Democrats say they'd love to run against Gingrich. Former House Speaker Nancy Pelosi says she has thousands of pages of dirt "when the time is right." Can Christian conservatives handle his married life? Do Tea Partiers want a lobbyist for Fannie and Freddie? What about his record as House Speaker?
