Here is some good news about Aspen Colorado adopted IRV.
On March 9, the Aspen, Colorado, city council voted to use Ranked Choice Voting in the city election set for May 5, 2009. The offices up are Mayor and two at-large city council seats. The Aspen voters had voted in 2007 to use Ranked Choice Voting, but the city council had to determine the details. The city spent a great deal of effort choosing among competing sets of rules.
