But if it's a close election, we're in for hell.
https://www.theatlantic.com/magazine/archive/2020/11/what-if-trump-refuses-concede/616424/The whole thing is a fascinating read (well, from afar at least) but just posting one bit here:
Republicans control both legislative chambers in the six most closely contested battleground states. Of those, Arizona and Florida have Republican governors, too. In Michigan, North Carolina, Pennsylvania, and Wisconsin, the governors are Democrats.
Foley, the Ohio State election scholar, has mapped the ripple effects if Republican legislators were to appoint Trump electors in defiance of the vote in states like Pennsylvania and Michigan. The Democratic governors would respond by certifying the official count, a routine exercise of their authority, and they would argue that legislators could not lawfully choose different electors after the vote had taken place. Their “certificates of ascertainment,” dispatched to the National Archives, would say that their states had appointed electors committed to Biden. Each competing set of electors would have the imprimatur of one branch of state government.
In Arizona, Secretary of State Katie Hobbs, who oversees elections, is a Democrat. She could assert her own power to certify the voting results and forward a slate of Biden electors. Even in Florida, which has unified Republican rule, electors pledged to Biden could meet and certify their own votes in hope of triggering a “controversy or contest” that would leave their state’s outcome to Congress. Much the same thing almost happened during the Florida recount battle of 2000. Republican Governor Jeb Bush certified electors for his brother, George W. Bush, on November 26 of that year, while litigation of the recount was still under way. Gore’s chief lawyer, Ronald Klain, responded by booking a room in the old Florida capitol building for Democratic electors to cast rival ballots for Gore. Only Gore’s concession, five days before the Electoral College vote, mooted that plan.
In any of these scenarios, the Electoral College would convene on December 14 without a consensus on who had legitimate claims to cast the deciding votes.
Rival slates of electors could hold mirror-image meetings in Harrisburg, Lansing, Tallahassee, or Phoenix, casting the same electoral votes on opposite sides. Each slate would transmit its ballots, as the Constitution provides, “to the seat of the government of the United States, directed to the President of the Senate.” The next move would belong to Vice President Mike Pence.
This would be a genuine constitutional crisis, the first but not the last of the Interregnum. “Then we get thrown into a world where anything could happen,” Norm Ornstein says.
Two men are claiming the presidency. The next occasion to settle the matter is more than three weeks away.
January 6 comes just after the new Congress is sworn in. Control of the Senate will be crucial to the presidency now.
Pence, as president of the Senate, would hold in his hands two conflicting electoral certificates from each of several swing states. The Twelfth Amendment says only this about what happens next: “The President of the Senate shall, in the presence of the Senate and the House of Representatives, open all the certificates and the votes shall then be counted.”
Note the passive voice. Who does the counting? Which certificates are counted?
The Trump team would take the position that the constitutional language leaves those questions to the vice president. This means that Pence has the unilateral power to announce his own reelection, and a second term for Trump. Democrats and legal scholars would denounce the self-dealing and point out that Congress filled the gaps in the Twelfth Amendment with the Electoral Count Act, which provides instructions for how to resolve this kind of dispute. The trouble with the instructions is that they are widely considered, in Foley’s words, to be “convoluted and impenetrable,” “confusing and ugly,” and “one of the strangest pieces of statutory language ever enacted by Congress.”
If the Interregnum is a contest in search of an umpire, it now has 535 of them, and a rule book that no one is sure how to read. The presiding officer is one of the players on the field.
Foley has produced a 25,000-word study in the Loyola University Chicago Law Journal that maps out the paths the ensuing fight could take if only one state’s electoral votes are in play.
If Democrats win back the Senate and hold the House, then all roads laid out in the Electoral Count Act lead eventually to a Biden presidency. The reverse applies if Republicans hold the Senate and unexpectedly win back the House. But if Congress remains split, there are conditions in which no decisive outcome is possible—no result that has clear force of law. Each party could cite a plausible reading of the rules in which its candidate has won. There is no tie-breaking vote.
How can it be that Congress slips into unbreakable deadlock? The law is a labyrinth in these parts, too intricate to map in a magazine article, but I can sketch one path.
Suppose Pennsylvania alone sends rival slates of electors, and their 20 votes will decide the presidency.
One reading of the Electoral Count Act says that Congress must recognize the electors certified by the governor, who is a Democrat, unless the House and Senate agree otherwise. The House will not agree otherwise, and so Biden wins Pennsylvania and the White House. But Pence pounds his gavel and rules against this reading of the law, instead favoring another, which holds that Congress must discard both contested slates of electors. The garbled statute can plausibly be read either way.
With Pennsylvania’s electors disqualified, 518 electoral votes remain. If Biden holds a narrow lead among them, he again claims the presidency, because he has “the greatest number of votes,” as the Twelfth Amendment prescribes. But Republicans point out that the same amendment requires “a majority of the whole number of electors.” The whole number of electors, Pence rules, is 538, and Biden is short of the required 270.
On this argument, no one has attained the presidency, and the decision is thrown to the House, with one vote per state. If the current partisan balance holds, 26 out of 50 votes will be for Trump.
Before Pence can move on from Pennsylvania to Rhode Island, which is next on the alphabetical list as Congress counts the vote, House Speaker Nancy Pelosi expels all senators from the floor of her chamber. Now Pence is prevented from completing the count “in the presence of” the House, as the Constitution requires. Pelosi announces plans to stall indefinitely. If the count is still incomplete on Inauguration Day, the speaker herself will become acting president.
Pelosi prepares to be sworn in on January 20 unless Pence reverses his ruling and accepts that Biden won. Pence does not budge. He reconvenes the Senate in another venue, with House Republicans squeezing in, and purports to complete the count, making Trump the president-elect. Three people now have supportable claims to the Oval Office.
There are other paths in the labyrinth. Many lead to dead ends.
This is the next constitutional crisis, graver than the one three weeks before, because the law and the Constitution provide for no other authority to consult. The Supreme Court may yet intervene, but it may also shy away from another traumatizing encounter with a fundamentally political question.
Sixty-four days have passed since the election. Stalemate reigns. Two weeks remain until Inauguration Day.
