On July 26, a U.S. District Court in Alabama issued an order in USA v State of Alabama, middle district, 2:12cv-179, in which all sides to the lawsuit agree that Alabama will make partial use of ranked-choice ballots in the upcoming special congressional election. Overseas absentee voters will receive both a ranked-choice primary ballot and a ranked-choice general election ballot. The order has no effect on voters who are not overseas.
Everyone involved is assuming that there will be a run-off primary, because of the large number of primary candidates who have already announced. Use of ranked-choice voting is the only practical way to keep to the state’s schedule for this special election intact, because of the federal law that requires that ballots be sent to overseas absentee voters at least 45 days before the primary or election. There also seems to be an assumption that there is a reasonable chance that minor party and/or independent candidates will qualify for the general election. That is why the order includes provision for ranked-choice voting (for overseas voters) for the general election as well. Here is a link to the court order. Thanks to Rick Hasen for the link.
