[Q]: Tampa, Florida (CNN) -- With Texas Gov. 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.
