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 with 54.5% of the vote, a reduced margin from Barack Obama's 58.06% in 2012. Conversely, Trump received 40.9% of the vote. 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.
