NO H8 Campaign...

Throughout his career, Sen. John McCain has been a staunch opponent of same-sex marriage. He opposed it during his 2008 presidential campaign and was vocal in his support for California's Proposition 8, which banned same-sex marriage in the state. His family, however, is increasingly on the other side of this hot-button issue.

McCain's daughter Meghan distanced herself from her father's stance last summer when she posed for an ad for NOH8, a gay rights campaign seeking to defeat Prop 8. Now his wife Cindy is joining in the effort and is also appearing in an ad for NOH8.

Cindy McCain isn't the first political spouse to do this, however. During the 2007 Democratic Primary, Elizabeth Edwards stated that she's "completely comfortable with gay marriage" even though her husband, John, then a candidate for the Democratic presidential nomination, was steadfastly against it. Michelle Obama has hinted at her support, saying in a speech that connected the gay rights struggle to civil rights: "The world as it is should be one that rejects discrimination of all kinds."

Prop 8 remains in the headlines because, though passed by California voters in November of 2008, it is now being legally challenged by another unlikely pairing. Ted Olson, the conservative lawyer who represented George W. Bush in the legal dispute over the 2000 election results, and David Boies, the lawyer who represented Al Gore in that same case, are leading the legal team. The case is currently in front of a federal court in San Francisco.
