Guys, honestly, you're completely delusional if you don't think the GOP, with control of the Senate, House and Presidency, wouldn't immediately repeal Obamacare.
Without 60 Senate seats, I don't think it would be as simple as you suggest. Particularly with respect to the Medicaid expansion, it seems like it would be difficult for the GOP to get cloture, and nuking the filibuster would be too controversial.
Nah, I think they'll abolish the filibuster as soon as they have full control over the presidency and congress. Mitch McConnell knows how powerful it can be in the opposition party's hands.
