Why is Eddie vedder mad at Ralph nader?

Eddie Vedder expressed frustration with Ralph Nader primarily due to Nader's decision to run as a third-party candidate in the 2000 presidential election. Vedder believed that Nader's candidacy siphoned votes away from Al Gore, potentially contributing to George W. Bush's victory. This anger stemmed from Vedder's view that Nader's run compromised the chance for progressive change in the U.S. and undermined the Democratic party's efforts.
