Among the distinguished academic historians to condemn Trump with videos on the Facebook page are Nell Irvin Painter, Michael Kazin, Joseph Ellis, Bernard Weisberger, and William Leuchtenburg. Other prominent, non-academic historians to contribute to the page include David McCullough, Ken Burns, and Robert Caro.

Not every historian is going along with the “Historians Against Trump” movement. Jonathan Zimmerman, a professor of education and history at New York University, voiced his disdain for Trump but could not support a movement he believed ran contrary to the ethics of the profession. “I think Trump is wrong for America, but I won’t pretend that my discipline has elucidated the one right way to look at him,” Zimmerman wrote in an op-ed for the Chronicle of Higher Education. “That goes against everything history stands for.”

As Shenkman noted, historians—and academics, in general—lean liberal politically. It shouldn’t be shocking that there few historians have publicly endorsed the Republican candidate for president, or that many of them have explicitly come out against him.

But only two? To put that in perspective, there were 8,751 full-time tenured or tenure-track historians at universities in the US last year, according to the American Historical Association. There are certainly more who support Trump but haven’t said so openly. But compared to the number who have publicly denounced him, Trump’s lack of support among the country’s foremost purveyors of historical perspective is disconcerting at best, and frightening at worst.

In the grand scheme of things, “historians”—as a voting bloc—is extremely small. They won’t swing the election one way or the other. That said, when the people who best know the consequences of someone like Donald Trump assuming political office have mobilized so firmly against him, perhaps it’s wise to listen.
