Connecticut ID requirements for voting by mail

COVID-19 Advisory: On May 20, 2020, Governor Lamont issued an executive order extending absentee voting eligibility to any registered voter in the August 11, 2020, primary if there is no "federally approved and widely available vaccine for prevention of COVID-19" at the time he or she requests an absentee ballot. The state will send out absentee ballot applications to every registered voter in the state and pay the postage for their ballots. All absentee ballots must be received by 8:00pm on Primary Election Day, August 11, 2020.
