Ralph Nader is getting the cold shoulder from Democrats on Capitol Hill, and some liberal activists have stopped contributing to the groups he founded. For example, Joan Claybrook, president of the Nader group Public Citizen, said that members of Congress were refusing to work with her group. Polls have shown that about half of the people who voted for Nader in presidential race would have voted for Al Gore had Nader not run, while only 20 percent would have voted for Bush. That means that Nader might have cost Gore the states of New Hampshire and Florida — and the presidency. Nader has asked Marcus Raskin of the Institute for Policy Studies, an anti-globalization think tank, to try to make peace with Democrats, enviros, and other lefties.
