The Republican campaign for president took a decisive turn after the Iowa caucuses on Jan. 3, with one contender dropping out of the race and others heading to New Hampshire and South Carolina for the next round of primaries.

Mitt Romney claimed a narrow victory in Iowa - he won by eight votes over Rick Santorum. John McCain, the Republican nominee from 2008, endorsed Romney after his Iowa victory.

Santorum, a former Senator from Pennsylvania, headed to New Hampshire hoping to ride the wave that earned him near-victory in Iowa. He has polled well with social conservatives and fundamentalist Christians and hopes he can continue to earn their votes in the primaries ahead.

Michele Bachmann, a Minnesota Congresswoman who won the Iowa straw poll in August but came in a distant sixth in the caucuses, suspended her campaign. Former Utah governor Jon Huntsman, who did not campaign in Iowa, is gearing up for New Hampshire, where he hopes his politically moderate views will appeal to voters.

The first five minutes of this video give a summary of the Iowa Caucus results, and the rest is an in-depth discussion about the future of the campaign.

"Last night, the people of Iowa spoke with a very clear voice. And so I have decided to stand aside. And I believe that we must rally around the person that our country and our party and our people select to be that standard-bearer." - Rep. Michele Bachmann (R-Minn.)

"I know the attacks are going to come. They're going to become more fast and furious now. And if you can't handle the heat now, you certainly can't handle the heat down the road." - Republican presidential candidate Mitt Romney
