Richmond, California, once one of the most crime-ridden cities in California, has had remarkable success in the last few years reducing murder and other serious crime. See this story in the Contra Costa Times. Richmond’s Mayor, Gayle McLaughlin, was elected to the City Council in 2004 while she was a registered Green Party member. She is still a registered Green Party member. She was elected Mayor in 2006 and re-elected in 2010.
Richmond is directly north of Berkeley, and in 2010 had a population of 103,701.
Congrats and a good job to McLaughlin, even though I as a libertarian disagree with most of her political views significantly.
