Six days of early voting began for municipal primaries being held in 21 Connecticut towns. Because these were party primaries, voters generally had to be registered members of the party whose primary they wanted to vote in. Early voting ran September 2–7, followed by Primary Day on September 9. Voters could use MyVote.CT.gov to check registration, polling locations and sample ballots.

Beginning July 1, Connecticut municipalities are required to provide video recording for secure absentee-ballot drop boxes during election periods. Municipalities generally must make recordings publicly available no later than five days after the final ballot retrieval and retain them for twelve months.

Connecticut’s new biennial budget provided additional funding and staffing for implementation of the Connecticut Voting Rights Act. Funding included personnel as well as technology, database and language-access expenses associated with administering the law.

Connecticut election officials reminded voters about the state’s three-month waiting period for people switching from one political party to another. To participate in the September 9 municipal primary as a member of a different party, an already-enrolled voter generally had to change affiliation by June 9. Unaffiliated voters were treated differently and could enroll in a party closer to the primary.
