The Green Party of California (GPCA) is a California political party. The party is led by a coordinating committee, and decisions are ultimately made by general assemblies. The GPCA is affiliated with the Green Party of the United States (GPUS).
As of September 5, 2025, there are 113,050 people registered to vote with Green party-preference, 0.49%, the seventh-largest. As of January 2022, there are twenty-nine California Green elected officials, including two elected-mayors and three in municipal councils.
History On February 4, 1990, Greens gathered at California State University, Sacramento, authored bylaws, founded the GPCA, and started a voter registration drive. The GPCA adopted the leaf-G logo which cartoonist Harry Driggs designed for the Green Party of San Francisco in the 1980s and which represents the letter G of the party name as a leaf.
Qualifying for elections On January 2, 1990, a month before foundation, Kent Smith sent notice to the secretary of state that the GPCA intends to qualify for the June 2, 1992 primary elections. At that time, there were 420 people registered to vote with Green preference and, to obtain this qualification, the party needed to have registrations of at least one percent of the vote in the previous gubernatorial general election, on December 31, 1991, the 154th day before the election.; . Following the 1990 election, this amounted to 78,992 people.
For the voter registration drive, the GPCA had two full-time fundraisers and hired Joe Louis Hoffman as full-time organizer.; . By November 11, 1991, the party had 50,000 people registered with GPCA preference. Late that November, the party received financial support and was able to pay people for obtaining registrations on a per-registration basis. By 1992, the party registered over 100,000 people with GPCA preference and thereby qualified, which it since has done continuously.State of California, Secretary of State 1992a, 2022a, pp. 8-2–8-3, and n.d.
GPCA members used the election qualification to run for offices, each facing the none of the above vote option, and all but one advanced to the general.; . Roger Donaldson ran for state assembly district 53, later decided against it, and sent out a letter urging voters to vote for none of the above instead of him. The party did not have candidates for the presidential, nor the senatorial races.
Party registrations were down to 91,342 people on October 4, 1993. They must have still been at least 78,992 people on January 4, 1994, for the party was qualified for the June 7, 1994 primary elections.
The 1994 gubernatorial general election was the party’s first opportunity to earn qualification through electoral result. If the party had a candidate running for a statewide-elected office that received at least two percent of the vote, the party would maintain qualification until the next gubernatorial primary, that is if registrations stayed at least one fifteenth of one percent (0.067%) of the statewide total. The GPCA did indeed have a party member, Margaret Garcia, who received 3.8% of the vote in the secretary of state election, 315,079 votes, well over the two percent threshold.
8,900,593 people voted in the 1994 general election, raising the amount of registrations that could qualify a party to 89,006 people. The GPCA did not have this amount on October 24, 1995, to qualify for the March 26, 1996 primary election in this way. Had Garcia not received the total that she did, the GPCA would have lost its qualification.
In 1995, GPCA leaders, including Mike Feinstein, offered Ralph Nader the party’s qualification, which Nader accepted, to become the first person to use the GPCA’s qualification in a presidential election. Margaret Garcia criticized this, saying “How ironic that a party espousing ‘future focus’ and long term planning is using Nader as a quick fix for our dwindling numbers.”qtd. in .
The GPCA finally met the registrations requirement in September 1996, and had 95,080 people registered with Green preference on October 7. The party has met the registration requirements since. The party has also had further electoral results that could maintain the party’s qualification, in every election since first qualifying.
Electoral milestones In 1996, Greens won seats to have a majority of the city council in Arcata, with three of five seats, lasting until 1998.; . In 2004, Greens won another council majority there, lasting until 2006. In 1999, Audie Bock won election for state assembly office in Assembly district 16. In 2000, Matt Gonzalez won election for county office in San Francisco (which is a consolidated city-county). In 2006, Gayle McLaughlin won election for mayoral office in Richmond.
Top-two primaries The GPCA opposed the June 8, 2010 primary election’s Proposition 14, which would remove access to the general elections from political parties, limiting access to the two candidates that received the most votes in a nonpartisan blanket primary, for California offices, i.e. not for the presidential race, nor local races. The proposition passed, faced court challenges, and survived those.
After Proposition 14’s implementation, three election cycles concluded without any Green candidates advancing from “top-two” primaries. Then, the 2018 US House elections saw Green Party candidates advance to the general elections. Laura Wells ran in the House district CA-13 election, advanced from a six-candidate primary, and received 34,257 votes in the general election, 11.6%.; . Kenneth Mejia ran in the House district CA-34 election, advanced from a three-candidate primary, and received 41,711 votes in the general election, 27.5%.; . And Rodolfo Cortes-Barragan ran in the House district CA-40 election, advanced from the primary, and received 27,511 votes in the general election, 22.7%.; . Each faced off against California Democratic Party (CDP) incumbent opponents in the general elections.
In 2020, Margaret Villa became the fourth Green candidate to advance from a top-two primary when she ran in the California State Assembly District 58 election, and she then received 41,100 votes in the general election, 25.1%.
In 2022, Michael Kerr became the fifth when he ran in the US House of Representatives District CA-10 election, and he then received 52,965 votes in the general election, 21.1%.
Platform The GPCA espouses green politics and the Ten Key Values of ecological wisdom, grassroots democracy, social justice, nonviolence, decentralization, community-based economics, feminism, respect for diversity, personal and global responsibility, and sustainability.
Organization The key values of social justice, grassroots democracy, decentralization, respect for diversity, feminism, and personal and global responsibility influence the GPCA’s structure of party membership being inclusive of California residents who are disenfranchised by the state in California or the US, party decisions being determined by general assemblies, limiting the role of its coordinating committees, entrusting its power to autonomous Green parties, composing coordinating committees through yearly, staggered-term elections of six women and six of any gender, and affiliating with the GPUS. The GPCA elects delegates to the Green National Convention (GNC) proportionally, rejecting the feature of artificial disproportionality resulting from, in examples, the general ticket or district elections.
The party’s most recent general assembly was held by video teleconference on November 12, 2022. As of January 13, 2023, Laura Wells and David Cobb are the party’s official spokespeople; the party’s treasurer is Justin Richardson; and Jared Laiti is the GPCA liaison to the secretary of state. The GPCA has a reference page of local-Green parties at .

The three counties in which the party has the most people registered are Los Angeles (24,829), San Diego (7,911), and Alameda counties (5,611). The counties in which the party has the highest percentages of the county’s registrations are Humboldt (1.68%), Mendocino (1.51%), and Trinity counties (1.03%).
During the 2016 presidential election, GPCA registrations dropped 30%, from nearly 110,000 to 77,868.; . Party spokesperson Mike Feinstein attributed the drop to outreach from the Sanders campaign, citing mailers sent to Greens. Thousands of California Greens decided to support Sanders’ endeavor for the presidential nomination of the Democratic Party of the United States of America (DPUSA) through voting, which, as there was a semi-closed election, necessitated reregistration either with CDP preference, or with no party preference (NPP), and then, requesting a crossover ballot. Gayle McLaughlin, who had won mayoral election as a Green, reregistered with NPP to vote for Sanders. The Peace and Freedom Party (PFP) saw a similar registration drop-off. The lowest point for the GPCA was around California’s primary elections in June, and by the end of the general election, the GPCA’s registrations rose back to 94,647 people, and the PFP rose back to original levels, also.
Jill Stein 2016 campaign staffer Bruce Dixon hypothesized that Sanders “aims to tie up activist energies and resources till the summer of 2016 when the only remaining choice will be the usual lesser of two evils.”2015 Dixon determined that Sanders was acting as a sheepdog candidate in favor of party politics within certain parties, the DPUSA in this case,; . despite the parties being opposed to the candidate’s cause,Dixon 2015 and 2016; ; . and that dissuades people from politics outside of those parties.; ; ; ; . These directives result in a lack of parties and electoral wins of candidates that would advance the sheepdog’s stated politics. They also result in captive constituencies; . that feel compelled to support candidates that they deem the lessers of two evils.Dixon 2015 and 2016. Sheepdogs may advocate their strategy before exiting the electoral contest, which could occur because of disqualification, including unsuccessful primary elections, or retraction of candidacy, as was advocated by Sanders before his 2016 disqualification.; ; ; .
