The 2016 United States presidential election in Connecticut was held on Tuesday, November 8, 2016, as part of the 2016 United States presidential election in which all 50 states plus the District of Columbia participated. Connecticut voters chose electors to represent them in the Electoral College via a popular vote, pitting the Republican Party's nominee, businessman Donald Trump, and running mate Indiana Governor Mike Pence against Democratic Party nominee, former Secretary of State Hillary Clinton, and her running mate Virginia Senator Tim Kaine. Connecticut has seven electoral votes in the Electoral College.
Clinton won the state by 13.64%, a reduced margin of victory from Obama's 17.33% in 2012. Clinton carried six of the state's eight counties; however, this was the first time a Republican presidential candidate had won Windham County since George H. W. Bush in 1988.
Trump's strongest county in the state was rural Litchfield County, while Clinton's biggest win was in adjacent, more urban Hartford County. Areas that swung in Clinton's favor were mainly concentrated in suburban Fairfield County, in towns like Greenwich, Darien, New Canaan, and Westport. This area is home to many New York City commuters. Other Democratic swings were in suburbs outside Hartford, such as Avon, Granby, East Granby, and Glastonbury, as well as outside New Haven, in towns like Guilford, Madison, and Woodbridge. This was the first time since 1888 that Darien and the first time since 1912 that Easton voted Democratic, largely due to opposition to the populist Trump among historically Republican affluent and educated voters. By contrast, areas that swung hard for Trump were mainly located in Windham County and northern New London County, in towns like Killingly, Sterling, Plainfield, and Voluntown. This mirrored a national trend of white working-class support for Trump.
