Dan Koh has conceded the 3rd Congressional District's Democratic primary, as a recount seemed set to confirm the race's initial results.
The Secretary of State's office announced Monday that certified results showed that Lori Trahan, of Westford, was up by 145 votes over Andover's Koh, after the Sept. 4 primary. A total of 88,823 votes were cast.
Koh filed for a town-by-town recount, which finished Monday.
"Out of 89,000 votes, it looks like we fell short by about 0.1%," Koh said in a statement Monday afternoon. "There’s no use in getting upset about the close margin – we can’t afford to. It’s time for us to unite behind Lori Trahan to be sure this seat stays Democratic."
Ten Democrats had competed in the primary.
Trahan previously served as chief of staff to former U.S. Rep. Marty Meehan.
Trahan will face Republican nominee Rick Green and unenrolled candidate Michael Mullen in November to fill the seat being vacated by retiring U.S. Rep. Niki Tsongas.
