The most interesting question right now is the extent to which Trump is actually MAGA. The Rest is Politics US had some interesting commentary on this.
The idea is that Trump uses his base in a way that benefits him. The evidence for that is his public flip-flopping over decades including donating to various democrat causes or campaigns. Trump isn’t actually interested in MAGA beyond how it serves him, and would be happy for it to die after his second term, so he can egotistically claim that it was all to do with him personally.
So what for his second term? He doesn’t need MAGA any longer. Hence why he’s cosying up to rich ‘friends’ and taking stances they disapprove of.
That implies next level degree chaos as Trump does whatever the hell he likes, pisses off his angry, armed base in the process, and to hell with the future.
