I don't think he will cancel the elections because early voting has already started in some States so it's getting a bit late. However I think he will do everything he can to disrupt the outcome and contest the results, as well as delay seating candidates. Assuming Democrats take the House and/or Senate he will ignore their subpoenas and investigations, drag everything through the courts, and try to block any kind of legislation they come up with. . He likes fighting so the Democrats will give him a tangible target to attack and his Truth Social posts will go into overdrive. Needless to say, he won't care about how the population is faring in the meantime and he will still be bogged down in Iran. His health is also noticeably deteriorating. His right arm twitches, his fingers seem to lock up at times. his face is sagging, he's slurring his words more and more, he can't walk in a straight line without lurching one way or the other, and he falls asleep in meetings all the time. I don't think he's going to last another two years.
