That’s actually the one single positive thing it’s almost possible to imagine Turmp doing. It can be explained in under ten words (“put everyone on Medicare”), it’s big and attention-getting, and Turmp isn’t beholden to any of the back-room stuff that would rule it out for normal Republicans (assuming Putin has no particular interest either way).
Obviously, as President, Turmp doesn’t make laws. But if he came out today and said that’s what had to happen, Republican lawmakers might just be caught off guard. They’d have to choose between disobeying their employers or risk being revealed as blatantly opposed to their own voters’ interests, and they might decide it was better to just go to their employers and say “sorry guys”.
I mean, if Turmp is going to randomly bulldoze the political norms that prevent, say, war with China, it’d be nice to think he could cause catastrophic changes where it would actually help. But I doubt it.
