I’ve mentioned this before - Carville is actually pretty savvy, but you cannot take anything he says for face value in the runup to an election. That’s all performance to get the vote out and get his ‘clients’ the win. Pure mercenary.
Post-election + a few weeks and you start to see him being a real person again, and real honest advice and observations flow.
He doesn’t take anything personally, and effectively uses/manipulates those that do.
Putting political views aside, I bet an off-the-record conversation with both Carville and Bill Clinton would be very interesting.
