The GoodParty.org Pledge

GoodParty.org only works with candidates and elected officials who are independent of both major parties and the influence of big money. Their positions on individual issues may vary, but they are eligible to take the pledge if they commit to being:

Heart

Independent

Candidates run and serve as nonpartisan, independent, or third-party candidates, not as Democrats or Republicans. They agree to not accept endorsements from either the Republican or Democratic party.

Users

People First

Candidates get a majority of their funding from individuals, not from political action committees (PACs), lobbies, unions, or corporations. Once elected, they pledge to focus on solving the problems facing their constituents, not serving themselves or special interests.

Star

Anti-Corruption

Candidates and officials pledge to uphold the highest level of integrity by being open, transparent, and accountable about their donors, positions, and progress. They agree to only serve the people, and to use the best tools and practices to do so.
