Donald Trump has done what Ronald Reagan did. He beat back a hostile press, smears by his opponent, outrage by foreign leaders, vast campaign spending by Wall Street and the wealthy one percent, and vows by actors and rock stars to leave the country if he was elected president.

Trump falls short of Reagan in many ways. He’s unlikely to be as consequential a president. But he has an opportunity in his first 100 days in the White House to put Washington on a new and entirely unexpected course. And harness an out-of-control federal bureaucracy—the so-called administrative state.
