Jake Auchincloss has won a packed primary to become the Democratic nominee in the race to fill the U.S. House seat being vacated by Rep. Joe Kennedy III in Massachusetts. Nearly 1 million voters, skittish over the coronavirus pandemic, used the mail option for Tuesdays primary. He was elected to the Newton City Council in 2015. Kennedy opted not to seek reelection so he could challenge incumbent U.S. Sen. Edward Markey in the Senate Democratic primary, but lost that bid Tuesday, becoming the first member of the Kennedy political dynasty to lose a congressional race in Massachusetts. The few other members of Massachusetts all-Democratic congressional delegation who had faced primary opponents Reps. Richard Neal, Stephen Lynch and Seth Moulton all breezed through Tuesdays runoff.

BOSTON A background in science specifically, infectious disease and epidemiology may not spring to mind as a key selling point for candidates hoping to land a seat in Congress. Kennedy is challenging incumbent U.S. Sen. Edward Markey in the states Democratic primary, creating an open race to fill his seat. I cant go anywhere in this district and not talk about anything but my experiences as an infectious disease doctor, he said. Goldstein said he also sees himself as part of a wave of younger Democratic candidates trying to push the party toward a more progressive agenda. Brookline resident Barbara Kamholz, a 48-year-old associate professor of psychiatry at the Boston University School of Medicine, said she's pleased with the variety of Democratic candidates running to fill Kennedys seat.
