A convenient liberal interpretation of the recent presidential election would have it that Mr. Trump won in large part because he managed to transform economic disadvantage into racial rage — the “whitelash” thesis. This is convenient because it sanctions a conviction of moral superiority and allows liberals to ignore what those voters said were their overriding concerns. It also encourages the fantasy that the Republican right is doomed to demographic extinction in the long run — which means liberals have only to wait for the country to fall into their laps. The surprisingly high percentage of the Latino vote that went to Mr. Trump should remind us that the longer ethnic groups are here in this country, the more politically diverse they become.

Finally, the whitelash thesis is convenient because it absolves liberals of not recognizing how their own obsession with diversity has encouraged white, rural, religious Americans to think of themselves as a disadvantaged group whose identity is being threatened or ignored.
