McCain finally makes to to The Late Show

It is a shame that it takes comedians like David Letterman to confront McCain on important issues like his association with G. Gordon Liddy.

Liddy "has paid his debt, he went to prison"
Does that change anything he has done in the past?
Bill Ayers never got convicted of anything, but republicans claim 'he never repented for what he did. Did Liddy?

Also observe that McCain quoted Ayers as saying ' I wish I had bombed more", which is incorrect, Ayers didn't say that. He said "I wish we had done more", no reference to bombing.

McCain's explanation to David about cancelling his appearance a couple of weeks ago was "I screwed up".

That's questionable. He lied.
