Guest: Franklin D. Roosevelt Jr.

It has been often said in jest that its role in New York politics has been to keep the Democratic Party honest and the Republican Party more liberal. Now, I suppose you could turn that to say that the Conservative Party, on whose line you ran for mayor a year and a half ago–their role, I suppose, would be to make the Republican Party more the party of McKinley or Adam Smith, and . . .” Buckley: “Are you against Adam Smith?” Roosevelt: “I think that he’s a bit out of date.”
