Most election rules in the US are set by states, many states (including the largest) have a citizen initiative process. Support by incumbent politicians is not necessary for reform that provides proportional representation with candidate-centered elections (e.g., STV rather than something like party-list-proportional) at the state level, which can provide the basis for creating pressure for the necessary federal reforms (e.g., modifying the federal statutory prohibition on multimember congressional districts -- created to stop the practice of states using multimember winner-take-all districts to avoid minority representation -- to allow multimember districts using methods that produce proportional results like STV) to at least allow states the option of providing better methods of electing federal representatives.
