I think he'll wholly jettison the Republican establishment this go around. His VP is going to be a sycophant, as will anyone else in his orbit. He's going to go on tour holding rallies every other week, talking about toilet flushing water and how they clean coal. He'll piss the Pentagon off by ending Ukraine involvement, and/or saying the quiet part outloud with regards to Palestine - something to the effect of it's ok for Israel to eradicate Palestine because white colonialists erased the natives in America and that worked out well for everyone since now there are Indian Casinos.
What else?
I could see the first year being the most chaotic. I kinda think he'll be absorbed back into the republican establishment again. He'll definitely pivot to going after China and Iran. He'll raise hell domestically with a ton of reactionary shit. Question is how long will it be until the reactionaries collapse due to infighting?
