The 2010 Connecticut gubernatorial election took place on November 2, 2010, to elect the 88th Governor of Connecticut. Incumbent Republican Governor Jodi Rell had announced in a press conference in Hartford on November 9, 2009, that she would not seek re-election in 2010. The sites Cook Political Report and CQ Politics both rated the election as a toss-up. This was the first open seat gubernatorial election in the state since 1994. As of 2026, this is the last time the Governor's office in Connecticut changed partisan control.
Gubernatorial primaries for the Republican and Democratic parties took place on August 10, 2010. The Democratic nominee, former Stamford Mayor Dan Malloy, narrowly won the general election, defeating Republican Thomas C. Foley. Foley conceded the race on November 8, 2010. Malloy became the first Democrat to be elected governor of Connecticut since 1986. With a margin of 0.7%, this election was also the second-closest race of the 2010 gubernatorial election cycle, behind only the election in Minnesota. As of 2026, this was the last time the Republican candidate won the counties of Fairfield and New London in a statewide election. Malloy was re-elected Governor in 2014 in a rematch with Foley.

General election
In Connecticut, candidates for governor and lieutenant governor are elected jointly on the same ballot line in the general election. In party primaries, however, they are nominated separately. Gubernatorial candidates often select an individual to be their preferred running mate prior to any such primaries, but their running mate in the general election is ultimately at the will of their party's primary electorate.
Prior to the state conventions and primaries, three gubernatorial candidates announced who they would wish to run with if so nominated to run for governor:
- Democrat Ned Lamont selected Simsbury First Selectwoman Mary Glassman to be his running mate on May 3.
- Democrat Dannel Malloy selected state comptroller Nancy Wyman to be his running mate on May 11.
- Republican Michael Fedele selected Danbury Mayor Mark Boughton, previously a fellow GOP candidate for governor, to be his running mate on May 17.
Additionally, one Republican, Lisa Wilson-Foley, ran for lieutenant governor without having been selected as a running mate by a gubernatorial candidate.
Prior to the Republican convention, Republican gubernatorial candidate Tom Foley decided not to name a running mate, stating that he believes that the state's tradition of a gubernatorial candidate naming a preferred running mate before party conventions and primaries is "out of date." While never named a preferred running for mate himself, Foley gave praise to both Michael Fedele's choice, Mark Boughton, and Lisa Wilson-Foley (of no relation).
At their respective party conventions, Boughton and Wyman won their party's endorsements on May 22, though both went on to face primary challenges. In the party primaries held on August 10, both party-endorsed candidates won, with Boughton defeating Wilson-Foley for the GOP nomination and Wyman winning the Democratic nod over Glassman.
The death penalty disagreement between Foley and Malloy gained additional attention due to the contemporaneous trial, conviction, and sentencing phase (which was under deliberation in the lead-up to Election Day) of Steven J. Hayes for a home invasion/murder in 2007 in Cheshire.
Candidates and running mates
- Democratic Party (also on line of the Working Families Party): Dannel Malloy – Nancy Wyman
- Republican Party: Thomas C. Foley – Mark Boughton
- Independent: Tom Marsh – Cicero Booker
Debates
On September 28, 2010, candidates Thomas C. Foley, Dannel Malloy, and Tom Marsh participated in the first gubernatorial debate of the 2010 race, a 50-minute, non-televised forum on education concerns in Hartford. In the debate, Foley stated that jobs and education would be his top priorities if elected governor, that more spending is not the solution to solve education-related problems, and that Malloy has "support[ed] the status quo" of teachers' unions. Malloy used the forum to advocate that schools report the amount of money spent in the classroom versus on school administration, stated that one "can be for reform and for teachers at the same time", and voiced support for a statewide universal pre-K program. Marsh stated that teachers' performance standards must improve and criticized the ratio that poorly performing doctors are removed from their jobs versus the rate at which underperforming teachers are.
Foley and Malloy met again two days later, on October 1, for a debate in Greenwich sponsored by the Greenwich, Stamford, and Norwalk chambers of commerce.
The first televised gubernatorial debate of the 2010 campaign took place on October 5, moderated by Fox News Channel chief political correspondent Carl Cameron and aired live on Fox Connecticut. Among other things in the debate in which the two opponents "clashed sharply," Foley voiced his support for retaining Connecticut's death penalty as is, pledging to veto abolishment bills placed on his desk as governor, while Malloy reiterated his opposition to capital punishment, though he stated he would not retroactively undo death sentences of individuals currently in the process. The candidates also took issue with each other's records, with Malloy accusing Foley of mismanagement while CEO of a Georgia textile mill and Foley labeling Malloy as a career politician who presided as mayor of Stamford during years in which the city had net job losses. State labor department figures have shown Stamford to have lost more than 5,000 net jobs during the 14-year period of Malloy's tenure as mayor. The Republican and the Democrat also took issue with statements and actions taken during the election season, with Foley stating that Malloy's pledge to cut gubernatorial staff by 15 percent would amount to only approximately five positions being cut and Malloy criticizing Foley for not naming a preferred running mate for the position of lieutenant governor. Malloy clarified that he had meant cutting from all positions the governor has a role in filling, stating that "about 600" positions was the real figure. Foley responded to Malloy's questioning over his running mate by stating that Republican primary voters placed Danbury mayor Mark Boughton in the position as Republican nominee for lieutenant governor, not him, but praised Boughton's experience.
A second televised debate was held between the Republican and the Democrat on October 13 in New London. A third, an afternoon debate broadcast live from Fairfield University on Connecticut Public Television, WFSB, and WNPR radio, occurred on October 19. The candidates met for a final time on October 26 for a televised debate aired on NBC 30.
Bridgeport ballot shortage
A dozen polling locations in the city of Bridgeport ran out of ballots on Election Day, leading to a ruling by Superior Court Judge Marshall K. Berger, Jr., for the polls to remain open at the affected polling sites until 10 p.m., two hours later than the normal statewide 8 p.m. closing time, in order for disenfranchised voters to return to vote on newly printed ballots. Bridgeport officials had initially ordered only 21,000 ballots, despite there being over 69,000 registered voters in the city.
With all votes counted, with the exception of Bridgeport, Republican Tom Foley held a slight lead in the popular vote (556,787 to 548,378). Once the ballots from Bridgeport were counted, Democrat Dan Malloy was declared the winner by Secretary of the State Susan Bysiewicz, who, according to the Stamford Advocate, based her announcement on preliminary, "informal totals. ... That does not include uncounted absentee ballots." Byseiwicz's announcement conflicted with the latest statewide tallies compiled by Foley's team and the non-partisan Associated Press, both of which indicated Foley to be in the lead by a thin margin.
Judge Berger did state in his ruling that all votes submitted after 8 p.m. would be counted as provisional ballots and kept separate from the others. The state Republican Party threatened a legal challenge.
On November 8, Foley, though still concerned over the election's handling and precise vote totals, conceded the election, stating, "The election on Tuesday was a conclusive victory for Dan Malloy, and this result should not be questioned."
