David Letterman continued his attack on Republican Presidential nominee John McCain, and I love it!

McCain stood Letterman up earlier in the week claiming to be rushing back to Washington to deal with the economic crisis. Instead, Senator McCain went else where at CBS (to Katie Couric) for an interview.

"Now I'm feeling like an ugly date," Letterman said on Thursday's "Late Show". "I feel used. I feel cheap. I feel sullied."

McCain spokeswoman Nicolle Wallace said the campaign "felt this wasn't a night for comedy."

"We deeply regret offending Mr. Letterman, but our candidate's priority at this moment is to focus on this crisis," Wallace said Thursday on NBC's "Today."

He also described socialite Paris Hilton — Thursday's guest whose celebrity was once used in a McCain campaign ad to mock Obama — as McCain's first choice for a running mate.

"Here's how it works: you don't come to see me? You don't come to see me? Well, we might not see you on Inauguration Day," Letterman said.

There's also a lot of buzz around Letterman's Top 10 List of McCain's Top 10 Blow-ups. I didn't watch "The Late Show" last night, and I forgot to set the DVR.

I did, however, find a Top 10 McCain blow-ups list delivered by Mitt Romney in the primary.
