The Obama campaign tries to link McCain to Jack Abramoff via Ralph Reed:

The McCain campaign hits back, invoking Bill Ayers:

“Barack Obama’s ad is ridiculous. Because of John McCain, corruption was exposed and people like Jack Abramoff went to jail.

“However, if Barack Obama wants to have a discussion about truly questionable associations, let’s start with his relationship with the unrepentant terrorist William Ayers, at whose home Obama’s political career was reportedly launched. Mr. Ayers was a leader of the Weather Underground, a terrorist group responsible for countless bombings against targets including the U.S. Capitol, the Pentagon and numerous police stations, courthouses and banks. In recent years, Mr. Ayers has stated, ‘I don’t regret setting bombs … I feel we didn’t do enough.’

“The question now is, will Barack Obama immediately call on the University of Illinois to release all of the records they are currently withholding to shed further light on Senator Obama’s relationship with this unrepentant terrorist?” --McCain spokesman Brian Rogers
