Trump won because white people are still the voting majority in this country and a measurable group of them can be riled up over imaginary racial/gender grievances to swing close elections. I might seem cynical on this point but everything else is just the window dressing that subset of the population told themselves to justify that other element. The post-election hypocrisy that they demonstrate is proof enough. The only issues, ethical or political, on which they have not flip flopped is the immigration conversation. Corruption, government intervention in the markets picking winners and losers, crime, building the economy, etc. Flip flopped on every single one of them...except immigration and tax cuts for the wealthy.
But to get back on track. I'm grad the general GOP voter is starting to think seriously about single payer. The ACA demonstrated for a lot of people that government intervention in the coverage aspect of the healthcare industry yielded real benefits for a lot of otherwise marginalized people.
We saw this during the election cycle when those random conversations were being shared about people wanting the government to repeal Obamacare but protect their ACA coverage. Obamacare does what it set out to do. And people know that it could be better but they have very little interest in going back to the pre-ACA model. So that only leaves one direction --> single payer.
