I, and around 1000 other people, saw him when he came to town. I would say that about half were hard core naderites (I live in gainesville, fl, a lefty stronghold). He was 45 minutes late arriving to the venue, and then he decided to talk to the press instead of coming on to the patiently waiting crowd. He was ranting, making incoherent jokes, skipping all over the place, and generally just being an asshole. One thing he said was that the Avian flu from from Asia is going to kill millions of people, making it much more dangerous than Terrorism. He also talked a lot about how he is the left's biggest defender and how all the other leftists who call him an egotistical has-been who is fvcking up the country by running are just a bunch of pussies. He went off stage and this nasally voiced dude comes on and asks "How many of you guys want to give $1000 to Ralph Nader, who has always been there for you? Come on give us your money, it will give you wings." Then he reduced the $ amounts for half an hour collecting money. I went to a 2000 rally and he was much more coherent and there wasn't any of the bullsh!t $ pandering. There also was a much bigger, and enthusiastic, turnout.
Four days later Michael Moore came to town and 12,000 people came to our 10,000 seat basketball arena. During the beginning this wacked out Nader guy walked around yelling "Shame! You've sold out Ralph Nader, your friend and brother!" Moore tried to compliment the guy and say that he was just foolish, but he wouldn't stop yelling. Moore said, "I'm trying to compliment you, now shut the fvck up!" and the place went MAD, people laughing, clapping, making noise. Moore went on afterwords to say how Nader and his followers are being very selfish and elitist, harping on and on about being so much smarter and better than everybody else, while doing nothing to help the country get past the reactionary right.
My opinion? Nader is slowly going insane. He was almost completely incoherent, and the only people really clapping and yelling for him were the zonked out hippies and neo-hippies who consider vegans who eat cooked food, sellouts. Doing the wave with 10,000 people at the moore rally, which basically was an anti-bush pep rally for Kerry, I realized that Nader won't be half as dangerous, or popular, as he was 4 years ago.
