Makes sense, since he's also an anti-Semite.
I'd like to see the evidence, before I accept that. If there's any basis to such a charge, I would imagine the Gore campaign would have made a big deal of it in 2000. As far as I know, they did not. Instead, I remember they made pretty scurrilous suggestions that Nader is homosexual (an idiotic tactic, considering the nature of Nader's potential constituency.)
