He's talking.. Imus got the questions in... he talked Viet Nam.. Imus doesnt have to slam him... thats our job :)
The point is that Kerry knew Imus wouldn't and that was why Kerry chose to appear. This says more about Kerry than it does about Imus.
Talking is not enough. Imus had an opportunity to challenge him on his obvious misstatements and omissions. There is a reason he goes on these shows--he gets to make his points to a freindly interviewer. We see what a liar Kerry is, but the general public doesn't get the same impression.
