The Green Party in the United States has won elected office mostly at the local level; most winners of public office in the United States who are considered Greens have won nonpartisan-ballot elections (that is, the winning Greens won offices in elections in which candidates were not identified on the ballot as affiliated with any political party). The highest-ranking Greens ever elected in the nation were Richard Carroll  who is a member of the Arkansas House of Representatives elected in 2008, John Eder who was a member of the Maine House of Representatives 2002-2006, and Audie Bock, who was elected to the California State Assembly in 1999 but switched her registration to Independent seven months later running as an independent in the 2000 election. In 2005, the Party had 305,000 registered members in states that allow party registration, as well as tens of thousands of members and contributors in the rest of the country. During the 2006 elections the party had ballot access in 31 states.
The Mountain Party came into existence as a ballot-qualified political party in 2000, when novelist Denise Giardina ran for Governor of West Virginia as a candidate of the party and won more than 1% of the vote. West Virginia's election laws say that when a party's candidate for governor achieves 1% or more of the vote for governor in the most recent general election, the party will be defined as ballot-qualified and can run candidates under its ballot label.
