Who would have thought Cindy McCain would have something in common with Kim Kardashian and Tila Tequila?

And, for once, we're not referring to Cindy's penchant for flaunting her cleavage in public!

Instead, like those outspoken reality stars, the wife of former Republican Presidential candidate John McCain has come out in favor of marriage equality.

She's the latest celebrity to pose for photographer Adam Bouska's NoH8 Campaign, which was created in response to the passage of Proposition 8 in California.

Writes Bouska:

"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 - marriage equality isn't a Republican issue any more than it is a Democratic issue.

It's about human rights, and everybody being treated equally in the eyes of the law that runs and protects this country."

Amen, Cindy! We apologize for ever referring to you as a Stepford Wife.
