Connecticut’s House delegation currently has 5 Democrats out of 5 seats. All 5 seats are up for election on November 3, 2026.
Connecticut is also represented in the U.S. Senate by Richard Blumenthal (D) and Chris Murphy (D).

Why Connecticut has five seats
Connecticut has five U.S. House seats. The 2020 Census counted 3,605,944 residents and the Census Bureau estimated 3,688,496 as of July 1, 2025. The state neither gained nor lost a seat in the apportionment that followed the 2020 Census. It last lost one after 2000.
Who draws the lines
Connecticut runs a three stage process written into its constitution. The legislature goes first. A bipartisan eight member committee prepares a plan, and the General Assembly must adopt it by a two thirds vote of each chamber by September 15 of the year following the census.
If the legislature misses that deadline, the governor appoints a nine member Reapportionment Commission. Each of the four legislative leaders designates two members and those eight choose a ninth. The plan is due by November 30 and does not go back to the legislature for approval. It has the force of law on publication.
If the commission also fails, the Secretary of the State notifies the Chief Justice and original jurisdiction passes to the Connecticut Supreme Court.
How the current map was actually drawn
All three stages ran in the last cycle. The General Assembly missed the September 15, 2021 deadline. The backup commission took over and agreed on the state House and Senate maps, then deadlocked on the congressional map. The Connecticut Supreme Court took jurisdiction and appointed Stanford law professor Nathaniel Persily as special master, instructing him to change existing districts only as much as necessary. The congressional map Connecticut uses today is the one that came out of that process.
On the 2026 ballot
All five House seats are on the ballot on November 3, 2026. All five are currently held by Democrats: John Larson, Joe Courtney, Rosa DeLauro, Jim Himes, and Jahana Hayes.
Neither U.S. Senate seat is up this year. Richard Blumenthal and Chris Murphy belong to classes that next face voters in 2028 and 2030.
