The Maine Green Party and the Maine Libertarian Party are both qualified, and each is entitled to its own primary. Filing for the June 2026 primaries has now closed. Only one Green Party member filed to run in the Green Party primary for any federal or state office, John Baldwin for state rep, 87th district. No Libertarian Party member filed to run in the Libertarian primary for any federal or state office.

Maine makes it very difficult for members of small qualified parties to get onto their own party’s primary ballot. The number of signatures for primary ballot access is just as high for qualified minor parties as it is for the two major parties.
