From Richard Winger at Ballot Access News:
The Populist Party existed from 1984 through 1994. Although the party ceased to exist in 1994, it continued to publish its monthly newspaper, the Nationalist Times, for another twenty-one years. However, on September 10 the paper announced that it will no longer be published.
The Populist Party’s strongest presidential run was in 1992, when it ran Bo Gritz for President. The Populist Party actually polled a higher share of the vote in the states where it was on the ballot than any other party other than the Democratic and Republican Parties. Gritz polled .31% in the states where he was on the ballot. But because he was only on the ballot in states containing 30% of the electorate that year, he only received 107,014, for fifth place behind Bill Clinton, George H. W. Bush, Ross Perot, and Andre Marrou.
