That a demagogue like Mr. Trump would emerge when there is a lot frustration in the lives of Americans who feel that their suffering is ignored isn’t without precedent. Which is why the greater sin of the Republican Party wasn’t that Mr. Trump won the nomination by carrying a plurality of votes in a large field. It was that people who surely knew better rallied to Mr. Trump once he became the nominee. Some advised him, others defended him and excused him, and still others tried to ignore him. Certain people acted worse than others. But in the end, they were all caught up in Mr. Trump’s ethical confusion and moral corruption. They didn’t pull him up; he pulled them down.
