What would you do if Trump somehow managed to overturn the election?

If Trump were to find a way to overturn the election, since it is obvious so far that there were no cases of significant voter fraud and, as Trump's own commission discovered, Republicans are just as guilty as anyone else, it would then fall in the laps of Congress to determine what happens next.  It is unlikely that they would support Trump in continuing as President so it would move down the line of succession and Nancy would become the first woman President of the US.

If Trump were to somehow overcome Congress and remain as President the US Constitution would become irrelevant and the formation of the US would change significantly.  Since the basic principle that created the US would no longer exist many states would leave the US either forming their own country or joining other countries.  The west coast would likely separate and either form it's own country comprised of California, Oregon, Washington and possibly Nevada or even join Canada.  Several northern states have already had indications of movements to join Canada if the US were to collapse.  Hawaii would probably declare it's independence and the remaining US States would become a 3rd world country under Trump with an economy similar to that of Venezuela.  The current economy of Venezuela is due, at least in part, to the method Hugo Chavez used to govern the country, a method very similar to that of Trump with one difference, Trump works for the ultra rich, Chavez opposed them.  US property overseas would be seized due to non-payment of debt, Trump himself would lose his overseas assets in all likely hood due to unpaid debts.  The US would no longer be a world power and a significant shift in the balance of power would ensue.

If there was actually fraud and other problems with the outcome of the election, I would be ecstatic if Trump actually won and I wouldn't be very surprised either.

Not possible. Every case has been thrown out of court. Because he has nothing. 

I plead the 5th, I won't incriminate myself.

That's not going to happen.

Believe in a God. Never going to happen. This is the real world.

First we kill the traitor electors/judges and their families. Then we kill the Trumps. Then we burn this third world shithole country to the ground!

It can't happen. Faithless electors are illegal in a majority of states. And the Supreme Court has no jurisdiction on this, per their own ruling in Gore v Bush.

Celebrate justice being done. It would be good to know election fraud was not just ignored because it's an inconvenient matter to deal with.

Faithless electors isn't overturning the election. The electoral college is the election.
