2020, the election campaigns have begun

On at least 2 scenarios, January 20th arrives with no clear winner in the White House, and the question about what happens to the nuclear weapons, or what the military will do, up in the air.

The constitution states that the president's term ends on midday, January 20th, irrespective of whether another one has been elected or not.
If the election is still being contested, you would hope that the Secret Service agents do the right thing and at the stroke of midday that day, they arrest Trump for tresspassing into the White House.
