Lawyers, mostly. How do we know? A terrific chart from Businessweek that breaks down all of the professions of the new Congress. There are 128 lawyers in the House and another 45 in the Senate. Somewhat remarkably, there only 55 career politicians in the House and another nine in the Senate. (The Fix would have bet the "over" on both of those numbers.) There's also one microbiologist, one carpenter and one physicist.
