The Daily Show is a useful place for people who like to see what has happened through time, in that the staffers are really good at picking up old video clips and playing "then and now" or "compare and contrast" with them. Here are two clips regarding the recent GOP convention.
This covers McCain's speech during the last day of the convention. I had heard highlights of it, and thought, "Hmm... Sounds like something I'd heard eight years ago..." And looky there! IT IS!
This second one is also great: It's Karl Rove vs. Karl Rove in his attack of proposed Democratic candidates due to their lack of experience, and praise of Sara Palin due to a more egregious lack of experience.
