It's decision day in Iowa. The caucuses are finally here, the first official test for the contenders in the republican presidential nomination process.
Mitt Romney and Ron Paul remain the front-runners, but as many as 40-percent of voters say they are still undecided.
Romney originally predicted a win tonight, but later said he was referring to winning the nomination, not about the caucus. Paul says he doesn't envision himself in the white house. And Rick Santorum has been surging in Iowa, but will emerge from the state with little money in campaign coffers and virtually no national infrastructure.
The first primary is next Tuesday in New Hampshire.
