Trump doesn't have to do anything to " make the ACA fail".

All that he or Ryan have to do is stand back and watch it continue to go down.  

"way too simple and has no place in todays hyperpartisan politics."   Both sides will continue to try to get political points and nothing will be done except a couple of partisan bills from each side will be drafted  that will have no chance of being passed whatsoever.  

Pelosi, the Freedom Caucus and you all have the same attitude.  "Everything or Nothing!"

It won't get 'fixed' or 'replaced'.  It will continue to fail because of its own costs and momentum.

Trump will talk about it in the 2018 elections and if the Freedom Caucus gets re-elected from all those Red Flyover States, it will continue in its death spiral.  

Meanwhile, back at the ranch, Oregon only has one health insurer from Bend to Idaho, and  the Oregon Legislature has to come up with the 5% Medicaid cost increase which the Feds are no longer providing because that is Obamacare.
