In 1968, George Wallace ran a nationalist campaign similar to that of Donald Trump's on the platform that he knows what it’s like to be at the wrong end of policies made by elites. Not surprisingly, appealing to the shrinking number of white, blue collar electorates is precisely why Trump doesn't want televised debates competing with NFL games.

"He wants people who are not sitting around thinking about the election because they’ve become so disillusioned by government," says John Dickerson, CBS News's political director, moderator of "Face the Nation," and the author of Whistlestop: My Favorite Stories from Presidential Campaign History (Twelve, 2016). He shares his take on presidential campaigns – today's and his top moments from the past – and what it was like to interview Trump.
