Doesn't matter who the VP pick is, the big wet boi is cooked.
Trump's followers will do some terrorism like they usually do, but the majority of them will become disenfranchised and go the way of the tea party - still present, still a pain in the ass, but ineffectual. They will devote their time to Trump's new talk show and he will sell them Trump hairy balls strong man supplements and other scams.
American empire will continue to expand, nothing will fundamentally change. Blue MAGA is the new order.
It does make me wonder how the Republican Party will come back from the dead again. They always do. Not even a 20 year ass kicking by the New Deal Democrats was enough to effectively end them.
They won't truly die until the material conditions for reactionary thinking die out too.
