The Democrats are taking their stand on the coronavirus crisis in an untenable position. It is like building a defensive redoubt in a valley surrounded by hills in the hands of the enemy (like the French at Dien Bien Phu in 1955, as President Eisenhower warned them). Whether this is tactical stupidity by the president’s enemies or strategic genius by the president or — more likely — a bit of both, is not clear except to insiders.
