Well he's riling up some international chaos, with Greenland and Mexico and whatnot. Wouldn't surprise me if some self-inflicted incident will be used as an excuse to "postpone" elections. From the article:

“So you say during the war, you can’t have elections,” Trump said to Zelensky at the time. “So let me just say, three and a half years from now—so you mean, if we happen to be in a war with somebody, no more elections? Oh, that’s good.”
