Incredibly, Ralph Nader has announced his candidacy for the Presidency of the United States.
There are other ways to voice one's opinions without running for president. Even John Kerry learned to leave the political stage after his loss in 2004 without having to be hit on the nose with a rolled-up newspaper too many times.
Forget winning, I don't think there's a way for him to even spoil the 2008 election for the Democrats. It's an utterly meaningless decision from which no good can come.
Don't go away mad, Ralph; just go away.
