It has been a strange few days on the Donald Trump front: He said something about himself that I actually believe and something about the economy that’s mostly true.

On the personal side, Trump has been sounding a lot like Adolf Hitler lately — I don’t mean his general tone, I mean his specific statement last week at a New Hampshire rally that immigrants are “poisoning the blood of our country”, echoing what Hitler wrote in Mein Kampf, almost word for word. (And if you think it was just a one-off, he said the same thing in a September interview.) But Trump claims never to have read Mein Kampf, and I believe him, just as I believe that he’s barely skimmed the Bible or any of the great books or, I would guess, The Art of the Deal. Pretty clearly, reading isn’t his thing.
