Rick Santorum, who has consistenly polled among the bottom tier of Republican presidential candidates, said Tuesday that he would exit the presidential race if matched up poorly against the other presidential contenders in the Iowa caucusus on January 3.

"If I finish dead last in the mix I'll go home but I don't think that's going to happen," he said Tuesday on the Des Moines radio station WHO.

The former Pennsylvania senator has been focusing his resources in Iowa and won endorsements from a number of the state's top conservatives, including its secretary of State, Matt Schultz (R), and Bob Vander Plaats, the head of the social conservative group The Family Leader.

He has been near the bottom in polls of the state, usually only topping Jon Huntsman, who is not competing in Iowa.

With Herman Cain gone and Jon Huntsman no longer a factor, and if our Polltracker is any indication... it looks like we may be saying farewell to Rick Santorum's campaign pretty quickly here.
