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.
They used reconciliation to get a bill to Obama for veto that eviscerated PPACA. So they can do something about it, just maybe not the typical full repeal.
