Connecticut was one of 15 Democratic state government trifectas at the start of 2025 legislative sessions. A state government trifecta occurs when one political party holds the governor's office, a majority in the state Senate, and a majority in the state House. For more information about state government trifectas, click here.

Connecticut was also one of seven state legislatures where Democrats had a veto-proof supermajority in both chambers. Veto overrides occur when a legislature votes to reverse a veto issued by an executive such as a governor or the president. If one party has a majority in a state legislature that is large enough to override a gubernatorial veto without any votes from members of the minority party, it is called a veto-proof majority or, sometimes, a supermajority.

Legislatively referred constitutional amendments

In every state but Delaware, voter approval is required to enact a constitutional amendment. In each state, the legislature has a process for referring constitutional amendments before voters. In 18 states, initiated constitutional amendments can be put on the ballot through a signature petition drive. There are also many other types of statewide measures.

The methods in which the Connecticut Constitution can be amended:

See also: Article XII and Article XIII of the Connecticut Constitution and Laws governing ballot measures in Connecticut

The Connecticut Constitution provides two mechanisms for amending the state's constitution—a legislative process, and a state constitutional convention. Connecticut requires a simple majority vote (50% plus 1) for voters to approve constitutional amendments. Connecticut does not feature the power of initiative for either initiated constitutional amendments or initiated state statutes.

Legislature

See also: Legislatively referred constitutional amendment

In Connecticut, a constitutional amendment can be referred to the ballot after one legislative session or two legislative sessions depending on the vote count.

When an amendment receives a 75% vote in both legislative chambers, the amendment goes on the ballot. That amounts to a minimum of 114 votes in the Connecticut House of Representatives and 27 votes in the Connecticut State Senate, assuming no vacancies.

When an amendment receives a simple majority vote in both legislative chambers, the amendment must pass during two successive legislative sessions to go on the ballot. That amounts to a minimum of 76 votes in the Connecticut House of Representatives and 19 votes in the Connecticut State Senate, assuming no vacancies.

Amendments do not require the governor's signature to be referred to the ballot.

Convention

See also: Convention-referred constitutional amendment

According to Article XIII of the Connecticut Constitution, a question about whether to hold a state constitutional convention is to automatically appear on the state's ballot every 20 years starting in 1978. Connecticut is one of 14 states that provides for an automatic constitutional convention question.

The table below shows the last and next automatic constitutional convention question election years:

State	Interval	Last question on the ballot	Next question on the ballot
Connecticut	20 years	2008	2028

The Legislature can also refer a constitutional convention question to the ballot. A two-thirds vote is required in each legislative chamber to refer a convention question to the ballot.

Proposals adopted at a state constitutional convention require voter approval.
