During a final 30-hour, five-state campaign tour, Al Gore appealed yesterday to enviros and other supporters of Green Party candidate Ralph Nader to join the "main" contest and vote for Gore over George W. Bush. Speaking on a syndicated radio show, Gore said, "I don’t like the argument that a vote for Nader is a vote for Bush, [but] I think it’s true. That’s why the Republicans are running TV ads for Nader." Some voters in swing states, particularly women, have received recorded phone messages from celebrities like Paul Newman and Robert Redford asking them to protect the environment by voting Democrat. The Sierra Club has called about 75,000 green-leaning voters in a dozen battleground states and sent email to 50,000 of its members, reminding them to vote. Meanwhile, at a rally yesterday in Harlem, N.Y., Nader continued to bash both Gore and Bush, saying a Nader vote in New York wouldn’t jeopardize what seems to be a certain Gore victory in the state.
