National Association of non-Partisan Reformers
The National Association of non-Partisan Reformers (NANR) works for a government that is representative of and responsive to the people by advancing electoral reforms and strategies that increase competition, participation, and accountability in the political system.
NANR works to transfer control of the electoral process back to the people by building an institutional knowledge base to empower collaborative strategies for challenging the institutionalized advantages of parties.
