Trump is now the Republican Party. He defines it and has virtually no opposition. Even the primary candidates mostly ran on the idea that Trump should win.
However, he also has no successor. When he dies, there’s going to be a scramble to figure out who can be the Trumpyest. There’s not going to be an orderly handover of power. I think it’s going to fracture their voter base between traditional conservatives, who will back someone like Ted Cruz, and the batshit crazy ones, who will back a Don Jr type.
Trump, for want of a better term, has the charisma that the entire party is hanging off of right now. Republicans have handed the fate of their party over to this man, because they have no real policies to sell to voters, and Trump voters don’t care about policy. Once he’s gone, there’s no one waiting in the wings to take over.
There’sno similar phenomenon on the Democratic side. There’s a handful of candidates from 2020 that I could see running again, including Kamala Harris and Pete Buttigieg, as well as newer candidates like Newsom. There might be an attempt to make Harris the heir apparent, but there’s no ride or die candidate the way the gop is with Trump.
The difficulty with that scenario is that the US is bound by two oceans and has a navy more powerful in some estimates than the rest of the navies in the world combined. Ukraine can be supplied because they’re contiguous with Western Europe. North Korea could be supplied by China, as could Vietnam. To supply the neo-confederates, Russia or China would have to cross an ocean and get past the US Navy, as well as the navies of other allied countries. Then they’d have to bring in the systems via either Mexico or Canada, both of which would be allied with the US.
I think you could imagine a scenario where they smuggle in small arms, but not artillery or other modern weapons systems.
