He's heavy-duty into a persona and irrationality to the point that seeing where he's most rational and authentic is pretty much impossible. I'd say some heavy Ne extravert, like an MBTI ENFP or ESTJ (so, an Fi/Te type) seems likely, since those types tend to have wacky personas if they're to be found in the American media more often than not, lol (think the Ed Schulz types on TV who are heavy into these intuitive-ish personas of a rather stereotypical nature).
