The Latest: GOP rep says he won election 'fair and square'

PORTLAND, Maine (AP) — The Latest on a lawsuit challenging Maine's voting system (all times local):

3:10 p.m.

Republican U.S. Rep. Bruce Poliquin says he won re-election "fair and square" and says he has a duty to fight Maine's new voting system that he says is unconstitutional.

Poliquin spoke to reporters Tuesday in Augusta after joining a lawsuit that seeks to overturn Maine's ranked-choice voting system, used for the first time last week in U.S. House and Senate elections.

The congressman told reporters in Augusta that "not addressing this important constitutional matter would be completely irresponsible and not doing my job." He called the system that lets voters rank all candidates on the ballot "convoluted" and "chaotic."

Poliquin received the most first-place votes and believes he should be declared the winner. But the voting system is required because neither he nor Democrat Jared Golden won an outright majority.

The campaign manager for Democratic congressional candidate Jared Golden says a lawsuit aimed at blocking Maine's voting system is "an affront to the law and to the people of Maine."

Jon Breed said Tuesday that Republican Rep. Bruce Poliquin knew the ranked-choice voting rules going into the election and that the people of Maine's 2nd Congressional District voted "in accordance with the law."

Poliquin, one of the plaintiffs, received more first-place votes than Golden on Election Day and believes he should be declared the winner. But the ranked-choice system requires additional voting rounds because neither he nor Golden won an outright majority.

The system lets voters rank candidates from first to last. It provides for eliminations of last-place candidates and reallocations of votes to ensure a majority winner. Maine election officials are in the process of scanning ballots for additional voting rounds.
