The Arizona Green Party is ballot-qualified and nominates by primary. Arizona requires petitions for candidates to get on the primary ballot of their own party. The only person who submitted a petition to be on the Green Party primary ballot for Governor, Larry Gist, seems assured of being the party’s nominee, because a challenge to his petition has been withdrawn. See this story. The challenge had been filed by a Democrat, but the challenge has been dropped because it appears Gist’s petition has enough valid signatures. Only independent voters, and registered Greens, were eligible to sign.
Activists in the Green Party do not know Gist, and were not involved in helping him get himself on the party’s primary ballot. He needed 1,231 signatures, and submitted 2,980.
