Republicans bring back Obama 'bitter' remarks in Pa. ad

A new ad from the super PAC backing House Republicans invokes President Obama's 2008 comments about "bitter" small-town Americans clinging to guns, religion and their prejudices against outsiders.

The ad is aimed at Democratic Rep. Mark Critz , but could have blowback for the president in the crucial western Pennsylvania district where it's running.

The president made those hidden-camera comments, during a 2008 fundraiser in California, in reference to Pennsylvania voters. Obama said at the time that, as jobs disappear in the area, "It's not surprising then they get bitter, they cling to guns or religion or antipathy to people who aren't like them or anti-immigrant sentiment or anti-trade sentiment as a way to explain their frustrations."

A spokesman for the Young Guns Action Network -- the group running the new ad -- told Fox News that the ad is set to begin airing in heavy rotation in the Pittsburgh media market later this week and Johnstown media market on Monday.

The district is key to Mitt Romney's hopes in Pennsylvania, with lots of coal production and many disaffected 2008 Obama voters.

The kicker on the ad: "A top Obama advisor even said Critz 'enjoys common values' with the Obama administration. Those aren't Southwestern Pennsylvania values. A vote for Mark Critz is a vote for Barack Obama."
