Appearing on Fox News on Wednesday morning, Karl Rove, the veteran Republican strategist, seemed a bit bemused. “We have two Presidencies under way,” he said. In one of them, Donald Trump was “looking strong and fulfilling his campaign promises,” Rove explained. He was referring to a series of executive orders that Trump had issued in policy areas ranging from health care to trade to the environment. While these edicts outraged many liberals and moderates, they were broadly in line with what the new President had pledged to do.
