For those who hadn't yet figured it out, the price of having a U.S. president who disdains expert opinion and who is impulsive, mendacious, not very smart, disturbed, uninformed, incurious, incompetent, intemperate, corrupt and a poor negotiator became irrefutably clear in recent days.

Three large developments from last Wednesday through Saturday unnerved even some of Donald Trump's Republican protectors, who had rationalized that, after all, he had cut taxes (mainly on the rich and corporations) and put two conservatives on the Supreme Court bench. But the dangers of having such a person in the Oval Office were now becoming harder to ignore.

All three big events were alarming, and on a bipartisan basis: Each was damaging to U.S. national interests, and each was avoidable. Worse, because they came in rapid succession, they created the sense that now (as opposed to previous alarms) the Trump presidency was truly spinning out of control.
