Anyone who sincerely believes that Nader is even a remotely serious candidate is obviously delusional and needs to have his/her head examined. Nader candidacy is a serious as, say, running to outlaw earthquakes in California or to give immortality to everyone. There is no point in discussing that issue.
Anyone in this country can say what he wants and with a little help from rich Republican donors even put his name on the ballot - that is the nature of the US electoral system. But anyone who votes for such a person and then complains that US population votes against their economic interests cannot be taken seriously.
A vote for Nader is worse than a vote for Bush - it is giving the left a reputation of the gang that cannot shoot straight or forming firing squads in the shape of a circle.
