Lori Trahan Defeats Dan Koh After Recount In 3rd Congressional District Primary

BOSTON (CBS/AP) – Lori Trahan has prevailed over Dan Koh in the Third Congressional District Democratic Primary.

After a hand recount, Secretary of State Bill Galvin announced Monday afternoon that "Lori Trahan will appear on the ballots as the Democratic nominee for Representative in Congress in the Third Congressional District."

Koh conceded shortly before, telling his supporters it's time to unite behind Trahan in the Third Congressional District Democratic Primary.

"There's no use in getting upset about the close margin – we can't afford to," Koh said in an email. "It's time for us to unite behind Lori Trahan to be sure this seat stays Democratic."

Trahan had a 122-vote lead over Koh before he requested a recount.

Ten candidates ran for Democratic Rep. Niki Tsongas's open congressional seat, which covers the district's 37 cities and towns from Lowell and Lawrence to Concord and suburbs west of Boston.

Koh is the former chief of staff to Boston Mayor Marty Walsh. Trahan was the chief of staff to former Rep. Marty Meehan.

The winner will face Republican Rick Green and independent candidate Mike Mullen in the November election.
