So, in Kennedy's case, he was a Catholic. And people thought after the Al Smith election and so forth that a Catholic couldn't win in the United States. But when he was able to win in West Virginia, he proved that a Catholic could win, even in a heavily Protestant state.

Reagan, people claimed, was too old to run for president and to be elected. But he proved himself such a vigorous campaigner in the primary system that he overcame those beliefs.

And so there are a lot of bad things. And in this campaign, if there's somebody you don't think should be nominated, if you think there's a coarseness to the campaign that's horrible, if you think it's creating voices around the world that seem to speak for America and damages in the world, you may say it's pretty horrible. On the other hand - what's the reverse?

And of course, in the case of Barack Obama, had he not won primaries - and particularly the heavily important caucus in Iowa - if the public hadn't shown that they were prepared to vote for a black president, we wouldn't have one today.

The reverse is a system in which you basically let people who were leaders in one way or another - people sometimes decried as party bosses, people who are part of special interests make the decision. And I think that's a worse system than the one we have.

To picture Roosevelt as a man at this time in his life - he felt he was old. He was 53 years old, feeling lonely and irrelevant. And all of a sudden, he takes on this campaign, and it becomes a crusade for popular government. And he ultimately goes on fire in the campaign, but he discovers he's up against all the old machine tactics that he used to use himself, and he has to let the public get involved. And he energizes the public through the most extreme kind of rhetoric, which truly brings him into the streets and onto his side.

But he [Franklin Roosevelt] specifically prohibits any black participation from the Deep South, something which just infuriates people who'd been his supporters and who'd believed in him and resides that he is just shockingly abandoned the right of the people to rule. It's a pretty horrible story in that respect.
