McCain gets promoted during his health care forum

During John McCain's forum opposing the health care reform proposed by President Obama, Shirley McAllister of Sun City asked a pointed question (emphasis mine) -

"Why are so many people opposed to a government-provided health care option? I believe you, Senator Kennedy...[crowd laughs]...I just promoted you...[more laughter]...Senator McCain, I'm sorry...I believe you have had access to government-provided health care for most of your life, and I would imagine that most of us here are on Medicare, and there may be some who would like to give up their Medicare. [shouts of "NO" from the crowd] No, none of us do, so what is so wrong with government-provided health care?"
