It's crunch time in the cornfields, and while polls show Newt Gingrich in fourth place, the candidate yesterday said he may still "pull off one of the greatest upsets in the history of the Iowa caucuses."

Mitt Romney, meanwhile, told supporters: "We're going to win this thing," the Des Moines Register reports. Campaign aides later said that the "thing" Romney meant was the nomination, not the Iowa caucuses.
As rivals talked victory, Ron Paul—who is, along with Romney and the surging Rick Santorum, considered a leading contender in Iowa—said his chances of winning the White House are slim, AP reports. Asked whether he could see himself in the Oval Office, he said: "Not really, but I think it's a possibility." Santorum drew large crowds as he made his final pitches, ABC reports. He urged Iowa's voters not to pick somebody purely on the basis of electability. "They may not be able to do what American needs to get done and that’s a victory that will feel very empty," he said.
