• You know what bugs me after a guy names his running mate? His opponents clamor for derogatory things the running mate said about the candidate earlier. Or what the candidate said of the running mate before he was a running mate.

    Here's my advice: Give it up -- it's a waste of time.

    Everyone knows the game. When you're running, you're criticizing.

    Kerry said Edwards had no experience.

    Edwards said Kerry had no new ideas.

    I recall George Bush Sr. complaining about Ronald Reagan's "voodoo economics" (search) and Lyndon Johnson calling JFK a novice. Both of them proved to be loyal number twos and both got to be number ones!
