Political parties and political designations in Massachusetts

In the Commonwealth of Massachusetts (a U.S. state), there are three recognized political parties and an additional 29 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.
