Massachusetts election law has two methods for a group to become a qualified party. The older method is for the group to run a candidate for statewide office. If that candidate polls 3% of the vote, then the ballot label for that candidate becomes a qualified party. This is how the Libertarian Party won this status in 2008; its U.S. Senate candidate polled over 3% of the vote.
The other method has existed only since 1990. A group can register its name, and then elections officials keep track of how many voters register as members of that group, on voter registration forms. If it gets registration of 1% of the state total, then it becomes qualified as well. No group has ever used this method.
Recently, the Independent Party filed paperwork to become eligible to have a voter registration tally. See this story. Massachusetts has never before had a ballot-qualified party named “Independent Party”, although there was an “Independent Voters Party” recognized after the 1990 election. It went off the ballot after the 1992 election because it didn’t poll as much as 3% for any statewide office in 1992 and also because it never attained registration of 1%.
