2. On Nov. 4, 2009, voters narrowly pass a ballot measure, Proposition 8, that overturns the May 15, 2008, California Supreme Court decision that said same-sex couples have a constitutional right to marry. Many supporters of same-sex marriage blame the results of the vote on an expensive campaign by the Mormon church, which opposes gay marriage. The approximately 18,000 marriage licenses already issued are still officially recognized as legal.
