## Analysis

Biden won the state by 20 points, a notable improvement from Hillary Clinton's 13-point win in the state in 2016. He fared especially well in Fairfield County, an ancestrally Republican area, as well as the Hartford suburbs. Biden also came within 5 points of flipping traditionally Republican Litchfield County, which had previously voted Democratic in 2008; and 4.2 points of flipping traditionally Democratic Windham County, which had previously voted Democratic in 2012.
Per exit polls by the Associated Press, Biden's strength in Connecticut came from college-educated and high income voters. Biden won a combined 70% in large cities and 62% in suburban areas, a key demographic in a heavily suburban state. Biden built on Hillary Clinton's gains in suburban Fairfield County, even flipping three towns: Trumbull, Brookfield, and Sherman. Trumbull and Brookfield last voted Democratic in 1964, while Sherman last voted Democratic in 2008.
Biden is the first presidential nominee ever to exceed 1 million votes in the state. Additionally, his total is currently the highest that any candidate in any race in Connecticut has received, surpassing the previous record of 1,008,714 that Richard Blumenthal received in his 2016 Senate race. At the same time, Biden became the first Democrat to win the White House without carrying Windham County since Woodrow Wilson in 1916. He also become the first Democrat to win without the town of Griswold since 1888, the first to win without the town of Sprague since 1892, the first to win without the towns of Killingly, Plainfield, Putnam, and Stafford since 1916, the first to win without Lisbon and Plainville since 1948, and the first to win without the town of Salem since 1960.
