[1][2] A total of six candidates stood in the primaries, including the preceding Green nominee for president in the 2012 presidential election, Jill Stein, who sought the nomination for a second time.

[3] On May 4, the Green Party of the United States formally recognized William Kreml and Jill Stein as candidates for its presidential nomination.

On June 15, the Stein campaign announced that it had received 203 delegates, enough to win the nomination on the first ballot at the National Convention.

The 2004 presidential election saw Green nominee David Cobb appear on ballots in 27 states plus the District of Columbia, and received 0.10% of the popular vote, losing out to many other candidates and parties on the ballot, including third-placed independent Ralph Nader, who had been the presidential nominee of the G/GPUSA in the 1996 and 2000 elections.

[6] In the 2008 election, Cynthia McKinney was nominated as the Green Party's candidate for the presidency and had ballot access to 32 states plus DC.

However, McKinney insignificantly improved upon Cobb's performance, capturing only 0.12% of the popular vote in an election that also saw Nader finish a strong third behind the Democratic and Republican parties.
