It’s one of the oft-cited lies, regurgitated by people and by the media (they’re lazy). Gore lost by 543 votes. 200,000 Florida Democrats voted for Bush! There were 8 third parties running, and ANY ONE of them got more than Gores 543-vote loss. Most of those who voted for Nader would have never voted for Gore, anyway. This lie is promulgated by the duopoly to discourage voters from voting for a third party.
