No petition to place a new party on the ballot has succeeded in Tennessee since 1968. The law requires a petition of 2.5% of the last gubernatorial vote, which is currently 33,844 signatures, and in the recent past has been over 40,000 signatures. Parties that have tried and failed to petition include the Libertarian, Green, Constitution, Americans Elect, and Reform Parties.
Tennessee is in the Sixth Circuit. As previously reported, on September 6, the Sixth Circuit ruled that Chris Graveline should be on the ballot as an independent for Michigan Attorney General, even though he failed to collect the required 30,000 signatures. The basis was that the Michigan requirement had been in effect for thirty years and had only been used successfully twice. It stands to reason that if requiring 30,000 signatures in Michigan (which is less than 1% of the last gubernatorial vote) is unconstitutional because the petition is used so seldom, it should be unconstitutional for Tennessee to require 2.5% of the last gubernational vote for new parties, given that the Tennessee hurdle has not been used once in the last 48 years.
