I believe that other inbound freshmen voted otherwise.
Hope they have fun being on no committees, being asked to sponsor no bills, having anything they propose crushed, and just generally being told to sit down and shut up. And then, with nothing to hang their hats on two years from now, they WILL be opposed in the primaries, those opponents will almost certainly get party money, and they’ll probably lose.
Congress is designed as an old boys’ club, it’s all about seniority and alliances, and the less of one you have the more of the other you desperately need. Freshmen have none of the former, and any that voted against Boehner will find they also have none of the later. It sucks, but that’s the world they chose to enter.
