Former presidential candidate John McCain's staunch opposition to gay marriage was one of the key parts of his presidential campaign. But it has become clear this was not supported in his own household. His daughter, Meghan (shown below), is a vocal advocate of gay rights. Now his wife, Cindy, has appeared in a poster campaign against California's proposition 8 – a law banning same-sex marriage.

Cindy McCain, aka Mrs. John McCain, appears in this poster with silver duct tape across her mouth and the campaign slogan, "NOH8", marked on her cheek.

Adam Bouska, the founder of the NOH8 campaign stated, "Aligning yourself with the platform of gay marriage as a Republican still tends to be very stigmatic, but Cindy McCain wanted to participate in the campaign to show people that party doesn't matter."

John McCain's office said in a statement that he respected the views of his family but remained opposed to gay marriage. "Senator McCain believes the sanctity of marriage is only defined as between one man and one woman," it said. In 2008 McCain backed a measure in his home state of Arizona to ban same-sex marriage.
