Well if Bohner has any balls he will immediately ask them all to a meeting and threaten to toss their sorry asses off any committees, then do it.
That’s what he did with the Conservatives a while back.
Yup. That's the best way to stop this thing (though, with some of these squishy RINOs, it may not be enough). I'm skeptical, though - I'm worried that Boehner wants it both ways - he wants a "clean" CR to pass, but wants to establish some credibility with conservatives, so he needs to oppose it. The dims' discharge maneuver gives him a way to do both, which is why I'm a bit pessimistic. I don't know if there are enough RINOs who are willing to sign the petition at this point, but if there are, I doubt Boehner is willing/able to exert enough pressure to stop them.
