Far from being in peril, I would guess, the Constitution is about to do what it was designed to do: Having successfully constrained a demagogic president throughout his term, in the usual ways — courts striking down executive orders, Supreme Court appointees acting independently, midterms handing the House to the Democrats — it is going to allow voters to eject him from the White House and install in his place dear, old Joe Normal.
For any of the “end of the Republic” scenarios to happen, this election needs to be close — close enough for the results in multiple states to be challengeable. But I struggle to see how this could come about.
If Jimmy Carter couldn’t get a second term after the small recession of January to July 1980, and if George H.W. Bush couldn’t get one after the comparably minor recession of July 1990 to March 1991, how on earth can Donald Trump get a second term after the disaster that has befallen the U.S. this year? Who gets re-elected after a pandemic that has killed more than 200,000 Americans and a recession that sent unemployment up to 14.7% in April, compared with peaks under Carter and the elder Bush of 7.8%? Trump’s latest jobs report has unemployment at 7.9%.
