What we’ve seen instead over the past three weeks is an awesome display of raw ignorance on every front. Worse, there’s no hint that either the White House or its allies in Congress see this as a problem. They appear to believe that expertise, or even basic familiarity with a subject, is for wimps; ignorance is strength. It’s not just the court defeat over immigration; Republican ignorance has turned what was supposed to be a blitzkrieg against Obamacare into a quagmire, to the great benefit of millions. And Mr. Trump’s imploding job approval might help slow the march to autocracy. But meanwhile, who’s in charge? Crises happen, and we have an intellectual vacuum at the top. Be afraid, be very afraid.
