Ralph Nader will appear as an independent presidential candidate on New Jersey's ballot, according to the state Division of Elections.
One challenge to keep Nader off the ballot was denied, said Paul Loriquet, a spokesman for the Attorney General's office. Loriquet did not know who filed the challenge. The deadline for filing challenges to a person's candidacy was Monday.
Democratic organizations in several states, including Arizona and Pennsylvania, have waged legal battles to keep Nader's name off the ballot.
Many Democrats believe Nader cost them the White House in the 2000 presidential election.
They contend that Nader's Green Party candidacy took votes from Vice President Al Gore in Florida, where George W. Bush won by 537 votes. Nader received 97,488 votes in Florida.
Nader expects to be on the ballot in 43 states, enough to win the presidency.
