The Green Party is a ballot-qualified political party in California and most states in the U.S. You have the option to make a statement by registering Green when you register to vote. In California, this will have no effect on your voting choices at all, except in the presidential primary.
The Green Party of California attained ballot status in 1991, and the Green Party of Orange County was founded in 1995.

Here are some highlights of the GPOC’s history for which we happen to have pictures.
From 1997: Greens were the force behind founding the Orange County Nigerian Action Coalition: more than 15 organizations encouraging the boycott of Shell, the effective government of Nigeria, to end the occupation of Ogoni territory and bring down the Abacha dictatorship.
From 1998: Greens joined with Families to Amend California’s Three Strikes to push back against expensive “tough on crime” posturing and amend the most crippling “three strikes” law in the country.
2000: Nader Presidential Campaign and D2KLA
2001: First Green elected to office in Orange County
From November 2001: Local Greens played a large part in organizing what later became the Orange County Peace Coalition (OCPC), opposing the wasteful wars and police state practices that used 9/11 as an excuse.
