How important is it to POTUS to remain in the White House?
Would he trust state politicians to negate the fraudulent election he saw coming?
Courts?
US Congress?
DOJ?
Military?
What information would he need, and what actions could he take to ensure his next term in office?

Some are annoyed by questions without answers.
Questions are intended to get you to examine your underlying assumptions and consider possibilities you had not previously considered.

Some think the only solution is the courts.
Some think Trump's only hope are the state legislatures.
Some think our only hope is the military.
There are many possibilities.
With Trump, there are possibilities no one has considered.

I don't know how this will end, but from what I've learned about POTUS, I suspect it will have a conclusion no one anticipated.

The best evidence that something unexpected awaits us is Pompeo's confident declaration that the State Department is preparing for a 2nd Trump term. He knows something the rest of do not. So do other cabinet members and so does Mitch McConnell.
