Santorum serious about 2012 run

Former Sen. Rick Santorum (R-Pa.) met privately with a group of his top political advisers last week to discuss the possibility of a run for president in 2012, according to CNN.

The former senator, who lost his bid for reelection to Sen. Bob Casey (D) in 2006, has made repeated trips to all three early primary states in recent months. 

Longtime Santorum adviser John Brabender told CNN the senator is "actively considering" a 2012 bid. a

Still a favorite of many grassroots conservatives, Santorum has made four trips to Iowa this year alone. His leadership PAC also raised almost $400,000 during the second quarter of the year.

But while a slew of other potential GOP presidential contenders have donated tens of thousands of dollars to Republican candidates in 2010 through their PACs, Santorum has taken a somewhat different tack thus far.

Instead of spreading his PAC money around to candidates across the country, Santorum has spent close to $1 million on direct mail expenses to help build a national fundraising base that might aid his presidential run. His PAC spent almost all of what it raised during the second quarter. 

Santorum's America's Foundation PAC gave to just three Republican candidates during the second quarter of this year.

Santorum donated $1,000 to Senate candidates Roy Blunt and Sharron Angle. He also gave $1,000 to Iowa Republican Brenna Findley, a candidate for state Attorney General.
