Self-righteousness can also get things wrong. Especially with the possibility of Mr. Trump’s re-election, many liberals seem primed to write off nearly half the country as irredeemable. Admittedly, the president doesn’t make it easy. As a candidate, Mr. Trump made derogatory comments about Mexicans, and as president described some African countries with a vulgar epithet. But it is an unjustified leap to conclude that anyone who supports him in any way is racist, just as it would be a leap to say that anyone who supported Hillary Clinton was racist because she once made veiled references to “superpredators.”

Liberals are trapped in a self-reinforcing cycle. When they use their positions in American culture to lecture, judge and disdain, they push more people into an opposing coalition that liberals are increasingly prone to think of as deplorable. That only validates their own worst prejudices about the other America.

Those prejudices will be validated even more if Mr. Trump wins re-election in 2020, especially if he wins a popular majority. That’s not impossible: The president’s current approval ratings are at 42 percent, up from just a few months ago.

Liberals are inadvertently making that outcome more likely. It’s not too late to stop.
