Quite a few commentators and political figures have had the same thought and, surprisingly, most of them are conservatives. Max Boot, a right-leaning fellow at the Council on Foreign Relations went on Twitter to say that "Trump is a fascist." Jeb Bush's national security adviser, John Noonan, chimed in and characterized Mr. Trump's ideas as fascism. "Nothing else to call it," he tweeted. Right-wing radio host Steve Deace labeled Mr. Trump's subversion of religious liberty "creeping fascism." The New York Times' conservative columnist Russ Douthat also used the political "f" word in a column last week, and then retracted it briefly until deciding the retraction was premature in light of Mr. Trump's proposal to shut the door on all Muslims traveling to this country.
