Maine has it.
Poliquin led Golden by less than a point on the first count, but since neither candidate received 50 percent of the vote, the state’s ranked-choice voting system kicked in to determine the winner.
Peloquin won the seat by popular vote, but not over 50 percent. so lost the seat in rank voting.
The new system, which voters have twice approved at the ballot box, lets voters rank candidates in order of preference. If no one receives a majority, the last-place finisher is eliminated and his or her votes reallocated to the candidates whom voters ranked second. The process continues until someone secures more than 50 percent of the vote
