I am thinking one of two scenarios.
One, they create havoc with all the new illegal soldiers and try to stop the election from taking place.
Two, they cheat even harder than they did in 2020, and tell the American people to shove their objections where the sun don't shine.
Biden dies or is removed from office. Kamala becomes president with Newsom as veep. Trump will ultimately win 2024, but there will be much turmoil before he returns to the Oval Office.
