1. Trump calling Buchanan a "Hitler-lover" is enlightening because it explains why Trump, who barks a lot about PC culture, is actually terrified of being publicly perceived as a racist, hence him being a much softer leader than his rhetoric suggests
2. So Trump is actually an arch "movement conservative," in the sense that he takes ideas, doesn't credit people, dilutes their ideas, and turns them into a grift
3. National Review opposed Buchanan for the same ideological reasons they opposed Trump (who was an unserious, incompetent version of Buchanan), which merely reinforces the point that NR truly is the home of invertebrates and not so beautiful losers
