FALLS CHURCH, Va. — An electoral reform that has taken root in the iconoclastic states of Maine and Alaska could be gaining traction nationwide.

After decades of theoretical discussions among policy wonks, advocates of ranked-choice voting are looking to expand the concept.

They’re turning to Wisconsin, Virginia, Utah and other states, building on a successful campaign in Alaska last year.

Fueling the effort is voter disgust with the current crop of elected officials, particularly in Congress. Virginia congressman Don Beyer is a supporter.

He said momentum is building but it could be a decade or more before ranked-choice voting is available to many Americans.
