Rick Perry threatening to cement his standing atop the national polls, his rivals for the Republican presidential nomination aggressively sought to undermine his conservative credentials on Monday during the first-ever CNN/Tea Party debate in Florida. Perry repeatedly found himself in the crosshairs, as the field of candidates took turns attacking his positions on illegal immigration, Social Security, and his controversial 2007 push to vaccinate Texas schoolgirls against human papillomavirus, a common sexually transmitted disease that can lead to cervical cancer. Minnesota Rep. Michele Bachmann, whose standing among Republicans has slipped dramatically since Perry entered the race, said she was "offended" by Perry's executive order, which included an opt-out provision for parents who did not want the vaccine.NEW: Perry finds himself in the crosshairs as GOP candidates attack his positionsBachmann accuses Perry of helping a drug company through a vaccination orderRomney on Perry: Being dealt aces does not make a good poker playerPerry calls for Social Security reform but drops "Ponzi scheme" label
