Commissioners
Commissioners are appointed by the President and confirmed by the Senate.
By law, no more than three Commissioners can represent the same political party, and at least four votes are required for any official Commission action. This structure was created to encourage nonpartisan decisions.
Commissioners serve in staggered six-year terms; two seats are subject to appointment every two years. The Chair of the Commission changes every year, with no member serving more than once per term.
