On December 4, the California Secretary of State certified vote-counting equipment that is already being used in Alameda County, California, for the purpose of letting the city of Oakland use Instant Runoff Voting for its own city elections. See this story. The voters of Oakland voted to use IRV in 2006, so they have been waiting a long time. There will now be only one round of city elections in Oakland, to be held in November 2010.
Only charter cities in California may use IRV for their own elections. But, Oakland is a charter city.
