ralphdontrun.net makes a good case for Ralph Nader not to run this time around.
My wife feels very strongly that it was not his fault that Gore lost last time around arguing that it was up to Gore to earn the votes. He didn’t earn them, he didn’t win (and until she starts up her own weblog (hint, hint) you’ll have to make due with that paraphrase of her position on this). But until I get home and get an earful, I agree with this site. 🙂
