Massachusetts 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.

[1] In the general election, Clinton won Massachusetts with 60.01% of the vote, while Trump received 32.81%.

It also marked the fourth consecutive election in which both the Democratic and Republican vote shares in Massachusetts fell; since 2004, the combined vote shares of the two major parties in the Commonwealth have gradually declined from 98.72% to 94.32%.

Meanwhile, the New Bedford and Fall River areas and the western part of Massachusetts, particularly eastern Berkshire County, swung to Trump.

Hillary Clinton won every single pre-election poll by upper double digits.
