Political parties and political designations in Massachusetts Information
In the Commonwealth of Massachusetts (a U.S. state), there are four recognized political parties and an additional 25 political designations in which registered voters may choose to enroll. Voters may also choose to remain as " unenrolled voters" (i.e., independents). Political parties hold primary elections, while political designations do not. A political designation is a one-to-three word descriptive term which may appear next to candidates' names on election ballots. To be recognized as a political designation, fifty registered voters must file a document with the state seeking this status.
In Massachusetts, election ballots include the candidates' names followed by either the candidates' party or his or her "political designation"—a one-to-three word description that must be a other one-to-three word term whose recognition has been requested by fifty or more registered voters. In many cases, non-party designations include the word "party" in the designation. However, only four such designations actually correspond to organizations that are recognized by Massachusetts as political parties: the Republican Party, the Democratic Party, the Libertarian Party, and the Green-Rainbow Party.
Voters may change their enrollment status with their election official, with a deadline twenty days before an election. 
All registered voters may vote in general elections. Massachusetts voters enrolled in a particular party may vote only in that party's primary, and cannot cross-over to vote in another party's primary,  but "unenrolled" voters may cast a primary ballot for one of the three parties.   Political designations are treated as "unenrolled" voters for primary purposes, and so they too may choose to vote in one of the party primaries. 
Under Massachusetts law, a political designation is created when fifty registered Massachusetts voters "file a form with the Secretary of the Commonwealth requesting that they, or any other voters, may change their registration to such designation."  These non-party political designations may field candidates for statewide office, if they petition with a sufficient number of signatures (10,000).
