Is Donald Trump Pat Buchanan redux? Sure, Buchanan is outwardly pious, while Trump is . . . well, Trump. (Nobody ever doubted Buchanan’s anti-abortion bona fides, for example.) And while Buchanan, whatever you make of his politics, is undeniably a serious intellectual, Trump . . . well, at the very least, he did go to an Ivy League school!

That said, Trump’s current campaign and Buchanan’s in 1992 and 1996 have some deep similarities. Both are motivated by economic nationalism and hostility to immigration, illegal and otherwise.
