U.S. Senate and House

Sen. Ed Markey (D) was reelected with 62.5 percent of the vote, resulting in the crushing defeat of Republican Brian Herr.

U.S. Rep. James McGovern (D) ran an uncontested race for reelection. He will return to Washington, D.C., representing the Massachusetts 2nd Congressional District, which includes the town of Amherst.
