Connecticut is one of 11 states without early voting and one of only three whose state constitutions bar it.
Instituting early voting would require an amendment to the state constitution. Connecticut voters rejected such a change in 2014. An early voting amendment was endorsed by both houses of the Connecticut legislature in 2019, but the proposal did not pass in the Senate by the two-thirds majority required to include it on the November 2020 ballot, losing by a slim margin.
The state legislature is likely to revisit the issue again in 2021 and if an early voting amendment passes in that session, it will appear on the 2022 general election ballot. If a majority of Connecticut citizens voting on the amendment then approve it, it will become part of the state constitution and discussions about what form or forms of early voting might be available will move forward.
