Them both being dead is both convenient and conveniently suspicious. Since Trump is guarded by secret service, conspiracies would arise saying they (under Bidens order, or a Harris power grab) killed him. It would be completely absurd given the circumstances and no reputable source would support it, but people would believe it anyway and Fox would push the story. Widely broadcast funerals for each of them.

Then nothing… The conspiracies would flow, but nothing much would change.
