Iowa Race Set for Photo Finish

The Iowa caucuses are finally here, and it looks like a three-man dead heat. Mitt Romney and Ron Paul lead most polls neck and neck, with Rick Santorum rising fast. Erstwhile frontrunner Newt Gingrich, now in fourth, tried to lower expectations yesterday, saying he didn't think he would win Iowa, but then reversed his position and said he might “pull off one of the greatest upsets in the history of the Iowa caucuses.” Paul also tried to control expectations, saying he doesn't see himself in the Oval Office but that he thinks it’s a possibility.
