The Libertarian Party traditionally gets its presidential candidate on the ballot in all states, or almost all states. Its presidential candidate was on in 46 states in 1988, 50 states in 1992, 50 states in 1996, and 50 states in 2000 (although the presidential candidate listed in Arizona was someone other than the presidential candidate listed in the other 49 states). In 2004 the party got its presidential candidate on in all states except New Hampshire and Oklahoma.
The Green Party has never been as successful at that task as the Libertarian Party. The best it ever did was in 2000, when it got its presidential candidate on in 43 states. This is because the national Libertarian Party has a strong tradition of helping state affiliates with ballot access, whereas the Green Party does not have that tradition.
However, the national Green Party’s ballot access committee is now providing concrete help to some state parties. Last year it helped the Arkansas Green Party, and on February 10 it appropriated $4,000 for the Arizona Green Party. The Arizona Green Party now has 11,000 signatures on its party petition, but it needs 20,449, by March 6.
There is a good chance the Arizona deadline for the party petition is unconstitutional. Petition deadlines for new or previously unqualified parties, or for their nominees, that early (even for office other than president), have been declared unconstitutional in Alabama, Alaska, Arkansas, Indiana, Kentucky, Maryland, Massachusetts, Nebraska, Nevada, New Jersey, Ohio, and Pennsylvania.
No petition to qualify a party in Arizona has succeeded since 2000, when the Greens last did it. The Arizona legislature moved that petition deadline from May to March in 2000. Thus even if the Green Party effort falls short, it is worthwhile for it to make a maximum effort, and sue against the deadline if such a lawsuit becomes necessary.
