13. I consider that a distinct possibility already.
And it makes good sense to pursue it. Specifically, I expect Boehner and Mitch to have a lot of difficulty with "party discipline" as it is, they've been hit, clobbered, shellacked, shown to be impotent, so the fear factor is much reduced. So I expect individual Congresspersons, esp. Rs, to be looking to their own future interests, and we ought to welcome anybody willing to vote our way on board.
