If you have a taste for political conventions but can't stomache the completely choreographed charades that they've become, switch over to C-Span 2, which has been airing clips from conventions past. As I type, Dwight Eisenhower is addressing us from the year 1956. Among other things, this apparently entails extolling Richard Nixon's leadership on civil rights.
For history junkies only. You know who you are.
Update: You really can learn a lot this way. In over two decades of reading about Adlai Stevenson, I never realized just how unpleasant it was to listen to him speak.
