The number of active voters in Connecticut decreased by 0.8% this year, with some parties losing more affiliates than others.
The G.O.P. lost 1.3% of its active voters, or 6,258. Minor parties, which include the Libertarian, Green, Independent and Working Families parties, lost 2.6% of their ranks. The Democratic Party lost 0.4%, or 3,036, according to the Secretary of the State’s office.
About 61% of Connecticut’s population are “active voters,” meaning they’ve voted in the last four years and haven’t moved out of state or died.
About 41.5% of active voters are currently unaffiliated, about the same as in 2025.
To vote in a Connecticut primary, like the one coming up on Aug. 11, residents need to be registered with a party.
Registered Democrats will have the opportunity to vote in the gubernatorial primary pitting Rep. Josh Elliott against Gov. Ned Lamont, and depending on the district, the 1st Congressional District race or state legislative primaries in two Senate and seven House districts.
Republicans in the 4th and 5th Congressional districts have the opportunity to vote for their party’s candidates, and there are also state House races for one Senate and two House seats.
The deadline to switch party affiliation has already passed, but those who are unaffiliated can still join a party until noon on Aug. 10.
Residents aged 18-29 are the most likely age group to be unaffiliated at 47%. They are also the most likely to be affiliated with a minor party.
Registered Republican voters skew slightly older than Democrats. About 44% of Democratic voters are under 50, compared to 38% of Republicans. For both parties, 60- to 69-year-olds form their largest cohort.
