No one watching Friday’s Inauguration ceremony could miss the contrast between the gracious civility with which the incoming and outgoing presidents treated each other and the utter repudiation President Donald Trump’s Inaugural Address made of Barack Obama’s eight-year reign. You could hear it at the start of the 16-minute speech. Trump thanked the Obamas for their “magnificent” aid throughout the transition. He then pivoted, with a loaded “however,” to how momentous this particular change of chief executives really is. It’s not just a change of administrations or parties, Trump averred. “We are transferring power from Washington, D.C., and giving it back to you, the American people . . . . What truly matters is not which party controls our government, but whether our government is controlled by the people,” he said, echoing James Madison in Federalist 51.
