Obama is gone and it's the GOP running the show now. If they can't pass something (and clearly they have a pile of steaming dung) and they can't repeal Obamacare (hard to do with well over 50% approval), they'll sabotage it to make it fail and then stand proudly and say "I told you so!".
I'm about at the point that go ahead and pass that pile of dung bill so that the GOP can really own it and either reap the rewards of a successful bill or face the gallows if it fails. I'm starting to think they hate their own bill, though, and won't pass it because they are afraid. It's a big game of chicken and partisanship and the GOP is in line to get run over first.
