2020 United States presidential election in Massachusetts

The 2020 United States presidential election in Massachusetts was held on Tuesday, November 3, 2020, as part of the 2020 United States presidential election in which all 50 states plus the District of Columbia participated. Massachusetts voters chose electors to represent them in the Electoral College via a popular vote, pitting the Republican Party's nominee, incumbent President Donald Trump, and running mate Vice President Mike Pence against Democratic Party nominee, former Vice President Joe Biden, and his running mate California Senator Kamala Harris. Massachusetts has 11 electoral votes in the Electoral College.
Biden easily carried Massachusetts with a 33-point margin, the largest margin whereby any nominee had carried the state since 1964. Massachusetts was one of three states where Biden won every county, the other two being Rhode Island and Hawaii. It was the eighth election in a row that the Democratic candidate carried every single county in the state. It is also the highest percentage of the popular vote that a winning presidential candidate has received in the state since Lyndon B. Johnson won the state with over 70% of the vote back in 1964. It is also the second time that a presidential candidate has won Suffolk County with over 80% of the vote in presidential history after Lyndon B. Johnson won the county with over 80% of the vote back in 1964, and the second time that a presidential candidate has won Middlesex County with over 70% of the vote since 1964. In addition, Biden won the following counties with the highest percentage of the popular vote that was seen for a Democratic presidential candidate in history: Barnstable County, Dukes County, and Nantucket County. Biden won nearly 2.4 million votes, the most received by a Democrat in a presidential election in the state's history.
Massachusetts had been a Democratic-leaning state since 1928, and a Democratic stronghold since 1960, and has maintained extremely large Democratic margins since 1996, and this remained true in 2020, with Massachusetts being one of six states (along with Hawaii, Vermont, Maryland, California, and New York) that gave Biden over 60% of the vote. Massachusetts is ethnically diverse, highly urbanized, highly educated, and less religious. Per exit polls by the Associated Press, Biden's strength in Massachusetts came from college-educated voters, which he won with 74% of the vote, which carries particular weight in Massachusetts, as the state contains the highest proportion of graduates in the country. Trump's slip among suburban voters led Biden to carry almost every municipality in the Greater Boston area by at least 60% or more, while Trump carried only several towns on the South Shore and in Central Massachusetts. Biden won 301 of the 351 municipalities. Biden swept all demographic groups, garnering 63% of whites, 84% of Latinos, 58% of Catholics, 56% of Protestants, and 86% of Jewish voters. Trump had the worst vote share in Massachusetts of any Republican nominee since 1996, and slightly underperformed George W. Bush's 32.5% vote share in 2000.
Massachusetts was one of sixteen states where President Trump received less percentage of the vote than he did in the 2016 election.
