# Green Party The Green Party of the United States (organized nationally in 2001, with roots in 1980s state Green movements) is a left-of-Democratic third party built on the "four pillars" of ecological wisdom, social justice, grassroots democracy, and nonviolence. Its platform centers environmentalism and climate action, single-payer health care, demilitarization, and campaign-finance reform. Though it has never come close to winning the presidency, the Green Party is one of the most consequential third parties in modern American politics because of its **spoiler** role in close elections. [[Ralph Nader]]'s 2000 candidacy — drawing roughly 97,000 votes in Florida, a state decided by 537 — is the textbook case cited by Democrats who argue that left third-party votes hand elections to Republicans. Jill Stein's 2016 run drew similar accusations in the narrowly decided Rust Belt states. For this KB the Green Party is the **left-side mirror of the third-party spoiler dynamic** — the counterpart to right-side spoilers like the [[Reform Party]] — and a live example of how a winner-take-all, [[Duvergers Law]] system structurally punishes third parties and the voters who back them. Its recurring appearance in American elections also makes it a frequent target of disinformation narratives about vote-splitting. ## See Also - [[Reform Party]] — the contemporaneous right/center spoiler party - [[Bull Moose Party]] — the historic spoiler precedent - [[Libertarian Party]] — the other major active US third party - [[Sixth Party System]]
