Investigative reporter Barton Gellman describes a nightmare scenario that would sow chaos and destroy our democracy.

What if Trump refuses to concede? He has repeatedly said that mail-in ballots are fraudulent. He’s already predicted that, unless he wins, the election will be “rigged.”

Yesterday, he was asked directly if he would accept the results of the election, and he refused to say that he would.

Gellman writes:

In this election year of plague and recession and catastrophized politics, the mechanisms of decision are at meaningful risk of breaking down. Close students of election law and procedure are warning that conditions are ripe for a constitutional crisis that would leave the nation without an authoritative result. We have no fail-safe against that calamity. Thus the blinking red lights.

“We could well see a protracted postelection struggle in the courts and the streets if the results are close,” says Richard L. Hasen, a professor at the UC Irvine School of Law and the author of a recent book called Election Meltdown. “The kind of election meltdown we could see would be much worse than 2000’s Bush v. Gore case.”

A lot of people, including Joe Biden, the Democratic Party nominee, have mis­conceived the nature of the threat. They frame it as a concern, unthinkable for presidents past, that Trump might refuse to vacate the Oval Office if he loses. They generally conclude, as Biden has, that in that event the proper authorities “will escort him from the White House with great dispatch.”

The worst case, however, is not that Trump rejects the election outcome. The worst case is that he uses his power to prevent a decisive outcome against him. If Trump sheds all restraint, and if his Republican allies play the parts he assigns them, he could obstruct the emergence of a legally unambiguous victory for Biden in the Electoral College and then in Congress. He could prevent the formation of consensus about whether there is any outcome at all. He could seize on that un­certainty to hold on to power.

Trump’s state and national legal teams are already laying the groundwork for postelection maneuvers that would circumvent the results of the vote count in battleground states. Ambiguities in the Constitution and logic bombs in the Electoral Count Act make it possible to extend the dispute all the way to Inauguration Day, which would bring the nation to a precipice. The Twentieth Amendment is crystal clear that the president’s term in office “shall end” at noon on January 20, but two men could show up to be sworn in. One of them would arrive with all the tools and power of the presidency already in hand.

“We are not prepared for this at all,” Julian Zelizer, a Prince­ton professor of history and public affairs, told me. “We talk about it, some worry about it, and we imagine what it would be. But few people have actual answers to what happens if the machinery of democracy is used to prevent a legitimate resolution to the election.”

The article goes on to describe in detail how Trump and his allies are already planning to disrupt the election, tie up the count with lawsuits, discredit mail-in ballots, and, if necessary, call out armed mobs to intimidate voters. Gellman believes that Trump will never concede.

I hope the article is not behind a paywall.

It details the worst threat to our democracy in our lifetimes, maybe since the the Civil War, maybe ever.
