Your enrollment as a voter will affect the party primary in which you can vote during Presidential Primaries.
There are four political parties in Massachusetts. If you are enrolled in one of these political parties, you will find the following letter codes next to your name in the column marked "PARTY":
D - Democrat Party
R - Republican Party
J - Green-Rainbox Party
CC - United Independent Party
U - Unenrolled
Voters who are not enrolled in a party (commonly known as "Independent") are listed with the party code "U" in the PARTY column. Unenrolled voters and voters who are members of Political Designations (indicated by other letter codes) can choose which party’s ballot they would like to receive.
If you wish to change your party enrollment prior to any primary, you must do so in advance of the primary election and by completing a new voter registration form in person, by mail, or online at www.RegisterToVoteMA.com.
