LEAKED VIDEO: McCain Blows Off Letterman For Katie Couric

John McCain blew off David Letterman today because he said was getting back to Washington to address the economic crisis.

Only it turned out he wasn’t in Washington, he was still in New York — being interviewed by Katie Couric.

The attached YouTube is  "an hour of ridicule boiled down to nine minutes."

As Letterman watches him live with Couric, it looks like his head is about to explode.  McCain might be able to shrug off "one hundred years," but will he be able to survive  if Letterman’s rage and OCD start to intersect over his campaign?
