Supporters of John McCain have been trying to exploit the tie between Obama and Ayers.
A new ad sponsored by American Issues Project says that Obama and Ayers served together "on a left-wing board. Why would Barack Obama be friends with someone who bombed the Capitol and is proud of it? Do you know enough to elect Barack Obama?"
One of the board members at American Issues Project, Ed Failor Jr., was a paid consultant for McCain's campaign in Iowa last year.
In April, Obama said he "deplored" Ayers' actions in the 1960s and that "by the time I met him, he is a professor of education at the University of Illinois. We served on a board together that had Republicans, bankers, lawyers, focused on education."
