You are taking for granted that the interview is accurate and not biases same as the network who is judging him. It's easy to make someone sound like a babbling idiot with a little creative editing. I would not be to quick to judge because of what you read in an interview.
I like to play devils advocate because I have seen both sides of the coin and I know how quick people are to judge someone because of something they have heard, read or presume without a bit of proof or investigation.
