Democratic incumbent U.S. Rep. Rick Larsen continues to expand his lead over Republican challenger John Koster.
With new numbers posted Saturday night by Whatcom County, Larsen’s lead grew to 4,122 votes over Koster in the 2nd Congressional District race.
On election night, Larsen was trailing Koster. But he took the lead on Wednesday and his margin has been growing since.
Larsen is seeking his sixth term. The 2nd District spans the northern part of Western Washington from just north of Seattle to the border with Canada and includes the San Juan Islands.
