I don't know, maybe have Cuba invade Florida during the election and no one will realize until they notice a lack of weird-shit-from-Florida news stories. Then they think it's just the other side lying to them to try and get more votes. At which point the neighbouring states will annex themselves into Cuba as a way to "own the libs" and start cosplaying as communists because they think it's funny. Soon, the entire culture begins to adopt communist ideals while calling themselves conservatives. The federal army can't fight to get the states back because they ran out of ammunition sending it to Ukraine and Isn'treal, and the only way to get enough is to ask China. So they are left with two soldiers per gun, and three guns per bullet.

Biden and Trump die in the most milk-toast MMA match you have ever seen, and Terry Cruise wins the election, leading the nation into the greatest electrolyte manufacturing boon known to history.

This either happens or it doesn't, so there is like a 50% chance of this future becoming a reality.
