Hoover Institution fellow and award-winning historian Victor Davis Hanson joins the Manhattan Institute's Troy Senik to discuss the presidency of Donald Trump and Hanson's new book, The Case for Trump.

Hanson argues that our 45th president alone has the instinct and energy to upset the balance of American politics. "We could not survive a series of presidencies as volatile as Trump's," he writes, "but after decades of drift, America needs the outsider Trump to do what normal politicians would not and could not do."
