The ACA in my estimation will live on in some form, however Republican input will eventually happen.
The program as it stands won't work well enough to address the problem, so we'll come up with something.
The only way that will happen is if both sides get to take credit for it. That wont happen until both sides get to play a real role in its creation.
Once we figure out our budgetary issues, we will then need to game out how to put humpty dumpty back together (health care reform).
The scope of the problem will necessitate that it gets dealt with in at least the mid term political horizon. If it doesn't happen by 2016 and we take the WH (which is entirely possible, if libertarian populism continues its rise [go Rand]), we will eviscerate it and replace the internal machinery with what we want.
The only way neither of those things can happen, is if the Dems can get enough buy in on their own to make the program work.
That is why I say this program is all about buy in. Any why consequently, it's important that you guys weren't accepting Republican amendments during the legislative sessions that created the ACA.
So yea, it doesn't work to keep half the countries representative out of the legislative process on programs that need buy in from the whole country, not just dem voters, to work.
