The Massachusetts Green Party presidential primary on March 1 will list five candidates: Darryl Cherney, Sedinam Kinamo Christin Moyowasifza Curry, William Kreml, Kent Mesplay, and Jill Stein. See this post at Green Party Watch.
The party tells the Massachusetts Secretary of State which names to list. No petition or fee is required.
