After Iowa, Rick Santorum Trumpets Campaign's Momentum

Former U.S. Sen. Rick Santorum of Pennsylvania surprised more than a few pundits by placing fourth in the Iowa straw poll in Ames on Saturday. He is trumpeting his showing in a new web ad complete with a series of quotes looking to bolster his candidacy. Santorum is an underdog in the race but, as the debate on Thursday showed, he could be a factor in the race, especially as he has shown no reluctance to go after the other Republican candidates on social issues and foreign policy.
