BANGOR, Maine (AP) A federal judge says he’ll rule next week on Maine Republican Rep. Bruce Poliquin’s bid to nullify the outcome of the ranked balloting election that he lost.

U.S. District Judge Lance Walker announced the timeline for his decision after hearing more arguments from attorneys on Wednesday.

Poliquin contends the ranked-choice voting system used for the first time in U.S. House and Senate races in Maine is unconstitutional. He wants the judge to either declare him the winner or to order a second election for the 2nd Congressional District.

The judge previously declined to stop the vote tabulations, but Poliquin’s lawsuit remains alive.

Poliquin had the most first-round votes, but Democrat Jared Golden emerged as the winner after two trailing candidates were eliminated and votes were reassigned under the voting system.
