I don't think it's a myth. I have no doubt that Nader gave us Bush. Charlie Cook knows what he's talking about.
The total number of Nader voters was much lower than the number of registered Democrats who voted for Bush. Gore and the Democratic Party's complete failure to win over and mobilise traditional Democratic voters "gave us Bush". Gore was a terrible candidate. Your only counter argument has been an argument from authority, ie that a life long Democrat blames the opponents of the Democrats rather than the Democrats.
Screaming about Nader is always and everywhere just a demand that left wing voters should vote for corporate neoliberals forever.
