Obama is probably an INFP, and probably our first INFP president. (Clinton was the first xNFx, as an ENFP). Lawyers are all over the place on the MBTI table because Law is all over the place in terms of "personality type" of law. It's the *type* of law that may reveal what Type he prefers.

Lastly, the INFP is the "archetypal figurehead" type and frequently found in artists (particularly musicians and actors) and non-INFPs find themselves projecting their hopes and aspirations on such types because they're so easily absorbed by the cool, reserved, and observant cultural sponges that INFPs are.
