Is Cindy McCain hot enough to be a biker mama?

Yesterday John and Cindy McCain made a stop at the annual motorcycle rally in Sturgis, South Dakota.  John McCain joked that his wife should enter the "Miss Buffalo Chip" contest, a "beauty pageant" where the contestants often end up topless and/or in thongs. 

“I told her with a little luck that she could be the only woman to serve as First Lady and Miss Buffalo Chip,” John McCain told the crowd.  Cindy just waved.
