Retirements and political ambition have created at least two dozen open General Assembly seats—seven in the state Senate and 17 in the House.

Four Democratic and three Republican incumbents are not seeking reelection in the Senate. Four of the seven are retiring, with the other three seeking higher office.

open general assembly seatsIn the House, nine incumbents have announced they will not seek reelection, while eight are pursuing Senate seats or statewide office in the November state elections.

Democrats currently control 80 of the state House's 151 seats, while the state Senate is split 18-18 between Democrats and Republicans.

The departures create a number of leadership vacancies, including chair positions on key committees such as Labor and Public Employees, Environment, Energy and Technology, and Judiciary.

Two House Democrats Chase Senate Seat

The decision by Judiciary Committee co-chair Sen. Paul Doyle (D-Wethersfield) to run for state Attorney General opened a pair of House seats, with two Democrats jockeying to succeed him in the Senate.

Doyle, fellow Judiciary co-chair Rep. William Tong (D-Stamford), and former federal prosecutor Chris Mattei face an August 14 primary to determine the Democratic nominee for Attorney General.

Rep. Antonio Guerrera (D-Rocky Hill) and Rep. Matt Lesser (D-Middletown) are running for the 9th Senate District seat, which Doyle has held since 2007 after representing Wethersfield in the House from 1995-2006.

Guerrera, a nine-term incumbent and co-chair of the legislature's Transportation Committee, is the party's endorsed candidate in the Senate race.

He and Lesser, co-chair of the Banking Committee, will meet in an August 14 primary election. Lesser was first elected to the House in 2009.

Kennedy, Slossberg Step Down

Environment Committee co-chair Ted Kennedy, Jr. (D-Branford) is stepping down from the legislature after two terms in the Senate.

Sen. Gayle Slossberg (D-Milford), co-chair of the Education and Housing committees will not seek re-election after seven terms in the Senate.

Two-term state representative Pam Staneski (R-Milford) is running for Slossberg's 14th Senate District seat, but faces a primary against Milford Board of Alderman minority leader Anthony Giannattasio, who won the Republican endorsement.

Labor and Public Employees Committee co-chair Sen. Ed Gomes (D-Bridgeport) is leaving the Senate after serving from 2005-2012 before returning in 2015.

Rep. Rob Sampson (R-Wolcott) is leaving the House to run for the 16th Senate District seat vacated by Sen. Joe Markley (R-Plantsville).

Markley, co-chair of the Human Services Committee, is the GOP's endorsed candidate for Lieutenant Governor. He faces a party primary against New Britain mayor Erin Stewart and Darien First Selectwoman Jayme Stevenson.

Additional Senate, House Open Seats

Three-term senator Art Linares (R-Westbrook), co-chair of the Higher Education and Employment Advancement Committee, faces a primary for the Republican nomination for state Treasurer.

Retired investment executive Thad Gray won the GOP endorsement for treasurer at the party's nominating convention earlier this year.

Appropriations Committee ranking member Rep. Melissa Ziobron (R-East Haddam) is leaving the House after three terms to run for Linares' 33rd Senate District seat.

Public Safety Committee co-chair Sen. Tony. Guglielmo (R-Stafford Springs) is retiring after 26 years in the Senate.

Two-term state representative Mark Tweedie (R-Manchester) is leaving the House to challenge Sen. Steve Cassano (D-Manchester) for the 6th Senate District seat.

Rep. Prasad Srinivasan (R-Glastonbury) will not return to the House after failing to win the Republican nomination for governor.

Energy and Technology Committee co-chair Rep. Lonnie Reed (D-Branford) and Committee on Children co-chair Rep. Diana Urban also will not stand for reelection.
