Consider Larry Kudlow and Stephen Moore. In August, the two legendarily libertarian-minded economists attacked Mr. Trump, focusing on what they called Mr. Trump's "Fortress America platform." His trade policies threaten the global economic order, they warned. "We can't help wondering whether the recent panic in world financial markets is in part a result of the Trump assault on free trade," they mused. As for Mr. Trump's immigration policies, they could "hardly be further from the Reagan vision of America as a 'shining city on a hill.'"
