Former Sen. Santorum heading back to Iowa

Rick Santorum will make his eighth trip to Iowa next week as the former Pennsylvania senator continues testing the waters for a presidential bid.

Santorum will be in the Quad Cities Dec. 15-16 for meetings. He'll also address members of the Quad City Tea Party at an event in Bettendorf, Iowa, that's open to the media. 

Santorum recently indicated he was waiting on Sarah Palin before deciding to enter the 2012 GOP presidential primary field. "If she decides to get into the race, she will take a lot of air out of the room, that's for sure," Santorum told The Associated Press.
