FILE - In this Oct. 12, 2006 file photo, then-Sen. Rick Santorum, R-Pa., left, and his opponent Democrat Bob Casey confront each other during the taping of a debate at the KDKA television studio in Pittsburgh. Republican presidential candidate Rick Santorum is as unpopular in Pennsylvania today as he was six years ago, when home-state voters kicked him out of the Senate in a rout. That sour public perception may doom his fading chances of sticking around in the GOP presidential race, along with other hurdles that dot his path to a possible, and needed, victory in the April 24 primary.
