GETTYSBURG, Pa. (AP) -- Rick Santorum is as unpopular in Pennsylvania now as he was in 2006 when voters kicked him out of the Senate.
And that sour public perception may doom his fading chances of staying in the GOP presidential race, along with other hurdles dotting his path to a possible, and much-needed, victory in the state's April 24 primary.
Santorum failed to heal a rift with fiscal conservatives or reassure party leaders that he could temper his hard-line positions on social issues. He also faces a nearly insurmountable hurdle to stop Mitt Romney from becoming the GOP nominee.
None of that is deterring Santorum. Campaigning in Pennsylvania this week, the former senator said that his support in the state is strong and that he'll work hard to win the primary.
