AUGUSTA (AP) — A Marine Corps veteran and state lawmaker has the most first-place votes but it'll take additional tabulations to determine if he's earned the right to challenge Republican Rep. Bruce Poliquin in Maine's 2nd Congressional District.

Jared Golden, of Lewiston, had collected about 50 percent of the vote with about two-thirds of the votes counted. If there's no majority, then the ballots will be shipped to the state capital for additional tabulations next week under ranked-choice voting.

Lucas St. Clair, who pushed for a national monument, was trailing about 10 percentage points behind Golden. Book dealer Craig Olson trailed in third.

Golden joined the Marines after the Sept. 11, 2001, terrorist attacks and served in Iraq and Afghanistan. He was twice elected to the Maine House.
