The surprising thing about the constitutional crisis we’re now facing is that it took so long to happen. It was obvious from early on that the president of the United States is a would-be autocrat who accepts no limits on his power and considers criticism a form of treason, and he is backed by a party that has denied the legitimacy of its opposition for many years. Something like this moment was inevitable.
What still hangs in the balance is the outcome. And if democracy survives — which is by no means certain — it will largely be thanks to one unpredictable piece of good luck: Donald Trump’s mental deficiency.
