Tomorrow is the presidential election. It's been a tough campaign, with not a lot of humor.

But politicians, and their constituents, need a good sense of humor. In 1998, Bob Dole, the unsuccessful GOP nominee in 1996, compiled a book of presidential and political humor.

Now, Dole himself was hardly known for his comic genius. But when I interviewed him in 1998, I found out how funny even conservative Republicans can be.
