I think Roosevelt proves himself to be the ultimate political force in this book. He really wasn't for primaries until he realized it was the only way in which he could challenge a sitting president then it becomes his crusade, is to create the primaries and to call for the people to rule.

When he [Franklin Roosevelt] ultimately does not get the Republican Party nomination and decides to start his new Bull Moose Party, he does, for the first time, let black delegates be part of the party from elsewhere in the country.

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.

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?

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.

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.

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.
