Make America great again. This is, of course, the campaign slogan of Republican presidential candidate Donald Trump. But it was essentially the same message that Republican Herbert Hoover delivered as he campaigned for president in 1932. Hoover was campaigning hard against his Democratic rival, Franklin D. Roosevelt, and against FDR’s so-called New Deal. And most of Hoover’s conservative talking points have survived to the present day. We hear from the author of a new book that argues the fight against the New Deal launched modern conservatism and today’s Republican Party as we know it.
