I think there will certainly be an "election" in 2028. OTOH, I am sure the republican trifecta (presidency, House, Senate) and all of Trumps appointed cronies will do everything they can to redistrict everything possible to their advantage, disenfranchises as many voters as possible, and make it easier to appoint electors and throw out unfavorable votes.
Yeah, he doesn't need to 'end' democracy, when he can very easily (continue to) bend it to the point where it becomes an irrelevant pantomime. The system itself lends itself to that, as it was never intended to be a democracy in the first place - it was always supposed to be a wealth-and-race-based oligarchy. The only thing that's averted that till now has been various forms of struggles that occured external to that system.
