David Letterman ain't buyin' it.

In his characteristically witty style, David describes why he smells something fishy behind McCain's claim that he is "suspending his campaign" to go and save us from the mortgage crisis.

All jokes aside, David is spot on.  He raises some very good questions, like:

• Why did McCain have to cancel his campaign?  Can't his backup, Sarah Palin, carry on the campaign?  (Hint: No; that would involve giving the press access to her.)
• Why did McCain tell Letterman at the last minute that he could not appear on Letterman's show because he had to "race" back to Washington, but then stop on his way for an interview on with Katie Couric for the Evening News?  (Hint: Because the CBS Evening News is a great campaign stop.)
