Absolutely Bush lacks the intellect to debate Kerry. He might carry if off if he was actually sitting on Rove's knee, with Rove the ventriloquist putting words in his puppet's mouth.

What really broke me up was an interview with Bush last year, before Kerry had even become the dem nominee, in which Bush said he wouldn't have time for debates because he would be "too busy being president."
This from the president who set records for vacation time and fundraising trips.
