Santorum's tepid support in his home state does not bode well for his chances in 2012, especially given Obama's net negative job approval rating in the state. Forty-nine percent of Pennsylvanians disapprove of the way Obama is handling his presidency, versus 46% who approve.
Santorum lost his reelection bid in 2006, and it looks like voters there haven't changed their minds about him. Only 38% of respondents said they have a favorable opinion of him, versus 44% who have an unfavorable opinion of him.
Obama carried Pennsylvania in 2008 by 10 points. While reapportionment due to the census will strike one of the state's House seats by 2010, it will still hold a formidable 20 electoral votes.
The PPP poll was conducted January 3-5 among 547 Pennsylvania voters. It has a margin of error of 4.2%.
