I got this in an email release from the New America Foundation:

In California, where San Francisco became the state’s first Instant Runoff
Voting city in 2004, voters in the cities of Oakland and Davis approved the
idea, which would allow voters to rank their first, second, and third
choices for office. Oakland overwhelmingly supported the measure by 68% of
the returns, meaning voters will use Instant Runoff Voting for all local
offices in November 2008. The Davis measure was an advisory recommendation.

Elsewhere, voters in Minneapolis passed their ballot measure with 65%
support. And in Pierce County, Washington, voters supported the move to IRV
for their partisan county elections with 54% of the vote.
