Power 50: Annise Parker

The openly gay mayor of the United States' fourth largest city has been elected to her post three times, and was a progressive public official and an LGBT activist before that. Named one of the top 10 mayors in the world by the City Mayors Foundation in 2014 (the only U.S. mayor on the list), Parker was praised for making the city greener and more walkable, and for expanding nondiscrimination protections.
