One Senate seat is up for election in Massachusetts, held by a Democratic incumbent. Voters will also choose representatives for nine House seats, all of which are held by Democrats. And they will select a governor, an office currently held by a Republican. See Massachusetts’s primary results.
Sen. Elizabeth Warren (D), one of the Senate’s most liberal members, is expected to win reelection in deep-blue Massachusetts. Her opponent is state Rep. Geoff Diehl (R), who co-chaired Donald Trump’s presidential campaign in the state. Warren, a former Harvard law professor, has said she plans to “take a hard look” at a presidential run after the midterm election. But her campaign may have already started: In response to Trump's criticism of her claims of Native American ancestry, she released an ad in which she takes a DNA test.
Gov. Charlie Baker (R), one of the nation's most popular governors, is favored to win reelection, even as the Massachusetts congressional delegation is expected stay completely blue. He faces former state finance director Jay Gonzalez (D).
