O'Neill is not connected with the campaign in any way. He debated Kerry in 1971 on the Dick Cavett show over Kerry's "war crime accusations".
I suggest you go to C-Span and stream the video. You might want to also watch Kerry's testimony to Congress in 1971.
One other thing, O'Neill voted for Perot twice. He is an independent.
Read my post again - I was praising the guy, admitting he is much more credible than I thought he'd be. I was cynical about him to be begin with but now find him credible. He did a great job with Tony Snow.
