Former Sen. Rick Santorum (R-PA) is fueling speculation he's serious about a 2012 presidential run by forming a political action committee in Iowa to assist local candidates running for office.
Marc Ambinder: "It's easy to, ah, pooh-pooh, Santorum's chances for 2012. Santorum is off national radar screens, but he's got a national radio show and has kept a core of loyal fundraisers. But Iowa conservatives are finicky and tend to like to surprise prognosticators. And they do reward candidates who spend time getting to know them."
