MARC THIESSEN: ‘Hamilton’ and the implosion of the American left.

Hey Democrats, want help to rally the country around Donald Trump? Here’s a great idea: Have a crowd of wealthy, out-of-touch Manhattan liberals (who can afford $849 tickets to “Hamilton”) boo Vice President-elect Mike Pence while the cast of the Broadway show lectures him on diversity.

The Democratic Party’s alienation from the rest of America was on full display at the Richard Rodgers Theatre on Friday night. And the left seems completely oblivious to how ridiculous it looks to the rest of the United States. Professors at Yale and Columbia universities and other elite schools postpone exams and cancel classes for students who could not deal with the election results. Kids in Washington schools cut class with tacit approval from administrators to march in protest of the results of a free and fair election. School officials in Montgomery County offer grief counselors to “help students process any concerns or feelings they have about the election.” (Funny, I don’t recall anyone canceling exams or offering my kids grief counselors when Barack Obama was elected).

People in the American heartland see all this, and they shake their heads in disgust. Today’s Democrats have become a party of coastal elites completely disconnected from the rest of America.

And, seemingly, smug about it.
