Oh believe me it's entirely possible, not very probable, but if you can: - Intimidate/Supress Opposition - Limit Franchise - Employ agents to election fraud/other practical shenanigans (doesn't even have to be for your party, just make people distrust the system enough to make it unworkable, and you bet that's going to be possible if Trump weakens the electoral commission as he has multiple other quasi-executive orgs) - Intimidate electors in the college/undermine the electoral college (he did this once, he could probably do it better this time) - Use any form of military action (thanks to recent court rigging state militaries are seemingly able to be called up by the president with any phony excuse) - Pull the fire alarm, shout 'emergency!' and cancel elections/undermine them (few governors are going to willingly go against the Federal government, especially if the executive continues to Intimidate states) - Use a very favourable supreme court to wreck any number of constituonal roadblocks (as they already kind of had, with their recent decision to limit federal judge's power to the area they preside over) It is very possible for it to happen. I personally don't think the neo-fascism we see under Trump will ever extend to an actual fascist putsch or Putin-level election rigging, but it is a non-zero likelihood. Even if he fails, the supreme court's recent decisions, and decisions they'll make in the future, implies he'll get away scott free. Why wouldn't he tempt fate?
