Paul Ryan jabbed at President Barack Obama on the campaign trail Tuesday over a remark from four years ago about frustrated voters clinging to guns and religion. "I am a Catholic deer hunter. I am happy to be clinging to my guns and my religion," Ryan said at a campaign rally in Carnegie, Pa. The comment was a reference to comments Obama made at a fundraiser in April 2008 in San Francisco. Ryan spoke while visiting a steel-supply company. Mitt Romney, meanwhile, was attending private fundraisers to raise cash ahead of next week’s GOP convention. Obama was set to fire back at Romney’s vice presidential running mate over $115 billion in education cuts in Ryan’s budget plan later Tuesday, The Associated Press reported. Obama will appear at Capitol University in Columbus, Ohio and at a community college in Reno, Nevada.
