A primary election is an election in which registered voters select a candidate that they believe should be a political party's candidate for elected office to run in the general election. They are also used to choose convention delegates and party leaders. Primaries are state-level and local-level elections that take place prior to a general election. Massachusetts utilizes a semi-closed primary system where voters who are affiliated with a political party and unaffiliated voters may vote in a party's primary.[2][3]
For information about which offices are nominated via primary election, see this article.
In Massachusetts, most polling places are open from 7:00 a.m. to 8:00 p.m. However, municipalities may open their polls as early as 5:45 a.m. Anyone in line when the polls close must be allowed to vote.[4][5]
To vote in Massachusetts, one must be a United States citizen, a resident of Massachusetts, and at least 18 years old on or before Election Day. An individual also cannot be currently incarcerated due to a felony.[6]
The deadline for registration is 10 days prior to the election. A voter can register online, by mail, or in person. In-person registration occurs at the local office of town clerks, the election commission, or the board of registrars, as well as the Office of the Secretary of the Commonwealth Elections Division and the agency's regional offices. Pre-registration is available for individuals 16 years and older who meet all other requirements.[6]
Massachusetts automatically registers eligible individuals to vote through the Department of Motor Vehicles, division of medical assistance, health insurance connector authority, and other agencies that collect what state law defines as reliable citizenship information.[6] If the agency determines a person is a U.S. citizen, they send the individual's name to the election office and a confirmation notice is mailed to the voter in 2-3 weeks.[6]
Massachusetts has implemented an online voter registration system. Residents can register to vote by visiting this website.[7]
Massachusetts does not allow same-day voter registration.[8]
To register to vote in Massachusetts, you must be a resident of the state. State law does not specify a length of time for which you must have been a resident to be eligible.[6]
Massachusetts does not require proof of citizenship for voter registration. An individual must affirm that they are a U.S. citizen when registering to vote. According to the state's voter registration application, the penalty for an illegal registration is a "fine of not more than $10,000 or imprisonment for not more than 5 years, or both."[9]
All 49 states with voter registration systems require applicants to declare that they are U.S. citizens in order to register to vote in state and federal elections, under penalty of perjury or other punishment.[10] Seven states — Alabama, Arizona, Georgia, Kansas, Louisiana, New Hampshire, and Wyoming — have laws requiring verification of citizenship at the time of voter registration, whether in effect or not. One state, Ohio, requires proof of citizenship only when registering to vote at a Bureau of Motor Vehicles facility. In three states — California, Maryland, and Vermont — at least one local jurisdiction allows noncitizens to vote in some local elections. Noncitizens registering to vote in those elections must complete a voter registration application provided by the local jurisdiction and are not eligible to register as state or federal voters.
The Elections and Voting page, run by the Massachusetts Secretary of the Commonwealth office, allows residents to check their voter registration status online.
Massachusetts does not require voters to present identification (ID) while voting, in most cases.[11]
The federal Help America Vote Act requires that individuals in all 50 states who register to vote by mail and who have not voted previously in a federal election in their state must provide either their driver's license or a paycheck, bank statement, current utility bill, or government document showing their name and address. Individuals voting by mail must include a copy of one of those documents with their absentee/mail-in ballot.[12]
These requirements do not apply if an individual submitted a copy of their identification, their driver's license number or the last four digits of their Social Security number when registering to vote.
Voters will also be asked to show ID in the following circumstances:

Massachusetts permits early voting. Learn more by visiting this website.
Early voting allows citizens to cast their ballots in person at a polling place before an election. In states that permit no-excuse early voting, a voter does not have to provide an excuse for being unable to vote on Election Day. States that allow voters to cast no-excuse absentee/mail-in ballots in person are counted as no-excuse early voting states.
Forty-seven states and the District of Columbia permit no-excuse early voting. Alabama, Mississippi, and New Hampshire do not offer no-excuse early voting.
All voters are eligible to vote absentee/by-mail in Massachusetts. There are no special eligibility requirements for voting absentee/by-mail.[14]
Voters can request an absentee/mail-in ballot online, by mail, or by email or fax. Massachusetts sends an absentee/mail-in ballot application to all registered voters before statewide elections.[14] Applications must reach local election officials by 5 p.m. on the 5th business day before the election. Returned ballots must reach local election officials by the close of polls on Election Day to be counted. Returned absentee/mail-in ballots during the biennial state election in November can be received by local election officials up to three days after the election, provided they were postmarked by Election Day.[14]
