Whatever kind of president Donald J. Trump turns out to be, he will surely be no Harry S. Truman. Instead of the sign that Truman kept on his desk declaring that “The Buck Stops Here,” Trump should get one that says, “Don’t Blame Me” — embellished perhaps with the phony coat of arms he plastered on his Scottish golf course.

A month after he won the presidential election, Trump is happy to take credit for things he likes — like the recent rebound in the stock market or the jobs that may be saved at that infamous Carrier plant thanks to millions of dollars the taxpayers of Indiana are going to pay.

But he’s also showing the world that he has no intention of taking responsibility for the hard stuff. Don’t blame Trump, he said on Wednesday, for the deep divisions in American society.

“I’m not president yet, so I didn’t do anything to divide,” Trump said in a phone call to the “Today” show. (He called in to gloat about being named TIME Magazine’s person of the year, a distinction also given to the Ayatollah Ruhollah Khomeini, Yuri Andropov, Adolf Hitler and Joseph Stalin — twice.)
