Senator McCain or Sentator McChicken?

Senator McCain is quotes as saying that he doesn't think he'll debate with Gov. Huckabee. Why not Senator? Do you think that he'll run circles around you like he's run around every other single candidate? Do you not want to see the contrast of you, a life-long politician with someone who has actually had to work a few times in their lifetime? Who has bought and paid for you this time?
