You don't say that for a senator to be a great senator he has to vote against his constituency.

The point is that you see candidates running in these different kinds of contests. A primary shows you something that's different from a state party convention, which shows you something that is different than what a caucus shows you.

The original thing that fascinated me most was why we expect leaders, and especially presidents, at times to destroy themselves - and that's a sign of being a good leader or a good president. We usually don't expect that of almost anyone else in any profession, in particular, in public life.

To people who remember JFK's assassination, JFK Jr. will probably always be that boy saluting his father's coffin.

So if 1960 had occurred under the old convention system, Kennedy would have had a very hard time getting the Democratic nomination because he would have been rejected by all those people who had worked with him in Washington.

Lincoln was able to say, you know, "It will make me very unhappy if I lose the presidency, but I'm committed to larger things." If you look at candidates and say this is someone who can be happy to go back to their family or they have larger convictions. Franklin Roosevelt jeopardized his presidency by telling Americans in 1940, "We might have to fight Hitler." He loved being president, but he loved defending freedom more.

Then you get to the last half of the 20th century, Americans are getting very skeptical about their leaders and their institutions, and another place that is affected is parties and conventions.
