I have a suspicion that eventually Trump is going to decide to support single-payer.

Trump used to be a democrat. His children/top advisors were democrats. During the campaign Trump expressed support for a Canadian-style "socialized" healthcare system (before backing off when he realized that was an antithesis to the average GOP primary voter).

I have a bad feeling that, at some point, Trump is going to be frustrated enough to let Ivanka and company whisper in his ear that this could be his great legacy and he's going to join forces with Schumer and Pelosi and any "moderate" republicans he can to bring us "Medicare for all."
