An article by Cass Sunstein: Suppose that on Nov. 3, and for weeks thereafter, no one knows whether Donald Trump or Joe Biden has won the presidential election. To be more specific, suppose that as of Nov. 4, Trump is unquestionably ahead in the key states — say, Michigan, Wisconsin and Pennsylvania. But suppose, too, that as those states count absentee and mail-in ballots, it becomes clear that Biden has won. Predictably, Trump alleges fraud — and tweets that his supporters, and the country as a whole, should not allow “THE GREATEST FRAUD IN HISTORY.” Everything will ultimately turn on the vote of the Electoral College, scheduled for Dec. 14, and on what happens on Jan. 6, when Congress meets to declare the winner. But if we have a fierce dispute in late November and early December, how on earth do we get to a final decision in early January? The Electoral Count Act of 1887 was designed to answer that question. In my first column on this issue, I described what the ECA requires in the event of contested elections, and explained what the law is clear about. By giving the major authority to the states, and by outlining, step by step, what is supposed to happen, it sharply limits room for political maneuvering in Washington. Unfortunately, the act also leaves some important questions unresolved. A leading political scientist of the late 19th century even described it as “very confused, almost unintelligible.” That’s too harsh. But exactly how would the law handle an objection, by Trump and his campaign, that the election was “rigged” and that mail-in voting resulted in rampant fraud? The first question, and the most fundamental, is whether the act is constitutional. Many people think that it isn’t, and the Supreme Court has never ruled one way or another.
