Should Trump be defeated, it is his civic duty to follow Gore's example (as noted here

"Gore had every reason imaginable to challenge Bush v. Gore and the whole circumstances of the election. He was half a million votes ahead in the nationwide popular vote, and for more than a century the popular-vote winner had become president. The Florida secretary of state, who was in charge of the recount, was co-chairman of the Bush campaign in Florida. The governor of the state, Jeb Bush, was his opponent’s brother! The reasoning of the Supreme Court’s ruling was so nakedly results-oriented that the Court itself said that it should not be taken as a precedent in any future rulings.
And yet, Gore said: the Court has spoken; I accept the results. His statement on December 14, 2000, is all the more remarkable with the passing years:
Over the library of one of our great law schools is inscribed the motto: ''Not under man, but under God and law.'' That's the ruling principle of American freedom, the source of our democratic liberties. I've tried to make it my guide throughout this contest, as it has guided America's deliberations of all the complex issues of the past five weeks.
Now the U.S. Supreme Court has spoken. Let there be no doubt, while I strongly disagree with the court's decision, I accept it. I accept the finality of this outcome, which will be ratified next Monday in the Electoral College. And tonight, for the sake of our unity as a people and the strength of our democracy, I offer my concession.
I also accept my responsibility, which I will discharge unconditionally, to honor the new president-elect and do everything possible to help him bring Americans together in fulfillment of the great vision that our Declaration of Independence defines and that our Constitution affirms and defends."
