Houston, Texas has become the largest city in the United States to elect an openly gay mayor after City Controller Annise Parker was declared the winner of a runoff election tonight. Social conservatives fought her election, funding a campaign aimed at turning out likeminded voters to support her opponent, former city attorney Gene Locke. But Parker's endorsements from labor, police, women's, gay rights and other groups were echoed by the Houston Chronicle, the area's major daily newspaper, and her campaign ran a superior get-out-the-vote effort.
