Watertown voters heavily favored Middlesex County Sheriff Peter Koutoujian and state Sen. Will Brwnsberger In Tuesday’s fifth congressional district primary election in which they lost to state Sen. Katherine Clark of Melrose.
Clark was selected as the Democratic party's nominee in the December race to replace longtime Congressman Ed Markey, who was elected to the US Senate earlier this year.
Clark, , won the fifth congressional district with 32 percent of the vote in the seven-candidate field. Koutoujian was second with 22 percent; Brownsberger fourth with 14.6 percent.
Clark will face the GOP’s Frank Addivinola, who won the Republican primary Tuesday.
The turnout in Watertown was 23 percent.
In the Democratic primary, Koutoujian received 38 percent of the votes, Brownsberger, 30 percent and Clark 14 percent.
Both Koutoujian and Brownsberger call neighboring communities home. Koutoujian is a Waltham native, who represented his home town for 14 years in the state's House of Representative. Brownsberger grew up in Watertown and moved to Belmont in 1992, serving on the town's Board of Selectmen before he was elected to serve as a state Representative in 2007, and then a state Senator in 2011.
In Watertown, 451 registered Republicans cast ballots at the polls Tuesday, with half of their votes -- 228 -- going to Addivinola.
Clark is the strong favorite going into the December general election, as she runs in a liberal district north and west of Boston — one that voted by more than 30 percentage points for President Barack Obama over Mitt Romney last November.
Should Clark, 50, win on Dec. 10, she would become only the fifth woman in history to represent Massachusetts in the US House, the Globe reported. The seat represents a mostly suburban district, which covers all or part of 24 towns and cities from Winthrop to Holliston.
