That’s not the right question. There is nearly zero likelihood that healthcare will become effectively more open market than it is now. In terms of healthcare as a motivator for voting, the least worst option is not to go any further towards socialized healthcare. And even with Trump that one may not be on the table.
On the republican side unless Trump is primaried successfully by an actual free market capitalist, we’ll likely have to settle for the crony capitalist/status quo—if we’re lucky. If we’re unlucky, and the Democrats figute out how to socially engineer Trump, well, he could make things worse.
So the right question is, rank-order least worst. The answer to that question has all the dems tied for last place.
I have often thought it is really strange how fanatical the Dems are in their hatred of Trump instead of simply trying to woo him to their side. My biggest fear is that they would win back Congress and suddenly realize how easily they could work with him to get what they want.
