On February 27, American Values 24, the PAC that supports the candidacy of Robert F. Kennedy, Jr., said that it has finished petitions for him in Arizona and Georgia. Georgia requires 7,500 signatures for an independent or minor party presidential candidate. Arizona requires 42,303.
Generally, American Values 24 relies on paid circulators.
There are other instances in history when an organization has carried out petition drives for an independent candidate, without coordinating with that candidate. In 2004 the Michigan Republican Party circulated a petition to get Ralph Nader on the ballot as an independent candidate, and the Michigan state court of appeals ruled there was nothing illegal for a group to circulate a petition without consulting with the candidate. DeLeeuw v State Board of Canvassers, 688 NW 2d 847.
Also, in 1968, groups submitted petitions putting Eugene McCarthy on the ballot as an independent in many states, even though McCarthy did not want them to do that.
