Obama is willing to be interviewed by Bill O'Reilly. But McCain cancels an interview with Larry King. Hmm..... One has a reputation of doing his darnest to cutoff anyone he disagrees with and is a reporter many folks won't accept an interview with because of his hostile nature. The other is generally considered the fairest interviewer in country and allows the interviewee to answer the question. I think one person has something to hide and the other doesn't.
