I know many liberals, and two of them really are my best friends. Liberals make good movies and television shows. Their idealism has been an inspiration for me and many others. Many liberals are very smart. But they are not as smart, or as persuasive, as they think.

And a backlash against liberals — a backlash that most liberals don’t seem to realize they’re causing — is going to get President Trump re-elected.

People often vote against things instead of voting for them: against ideas, candidates and parties. Democrats, like Republicans, appreciate this whenever they portray their opponents as negatively as possible. But members of political tribes seem to have trouble recognizing that they, too, can push people away and energize them to vote for the other side. Nowhere is this more on display today than in liberal control of the commanding heights of American culture.

Take the past few weeks. At the White House Correspondents’ Association dinner in Washington, the comedian Michelle Wolf landed some punch lines that were funny and some that weren’t. But people reacted less to her talent and more to the liberal politics that she personified. For every viewer who loved her Trump bashing, there seemed to be at least one other put off by the one-sidedness of her routine. Then, when Kanye West publicly rethought his ideological commitments, prominent liberals criticized him for speaking on the topic at all. Maxine Waters, a Democratic congresswoman from California, remarked that “sometimes Kanye West talks out of turn” and should “maybe not have so much to say.”
