Looks like John McCain’s “suspended presidential campaign” just lost the war hero a vote.

Late night host David Letterman is kinda pissed that the Republican senator cancelled a Wednesday night appearance on the Late Show, (on ultra short notice, thank you very much) in order to “race back to Washington” and help the House hash out an economic bailout plan–especially since he still managed to make it into a scheduled interview with CBS Evening News anchor Katie Couric.

Watch Letterman react to being blown off for Katie Couric in this video from tonight’s episode of the Late Show.
