It's not unfathomable for both sides to make some concessions. Obviously nobody is going to sign off on giving the other everything they want
The democrats are in a position of power here. The ACA is the law on the books. There is no reason to concede anything as long as republican plans keep polling in the teens.
The repeal nonsense needs to stop. If Heller votes for repeal, he loses in 2018. He might lose anyway. 2-3 other republican senators are in the same boat.
If they stop talking about repeal, and start talking about fixing the ACA, moderate democrats will at least come to the table.
Raise the bar for medicaid to include more people, and get rid of subsidies. Then go after big pharm together.
