(CNN) - Cindy McCain, the wife of the 2008 Republican presidential candidate, has posed for a Web site promoting same-sex marriage.
McCain, who's married to Arizona Sen. John McCain, appears in a photograph on the site with a piece of silver duct tape over her mouth and the slogan "No H8" written on her cheek.
The site's owners were stunned when Mrs. McCain came to them with the idea of posing for them, they said when posting her photo Wednesday.
"We've often been surprised at some of the different individuals who have approached us showing their support. Few, though, have surprised us more than Cindy McCain," wrote Adam Bouska and Jeff Parshley.
"The McCains are one of the most well-known Republican families in recent history, and for Mrs. McCain to have reached out to us to offer her support truly means a lot," they wrote.
"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," they argued, saying it was "about human rights."
The McCains' daughter Meghan, a vocal supporter of same-sex marriage, also appears on the site.
"I couldn't be more proud of my mother for posing for the NOH8 campaign. I think more Republicans need to start taking a stand for equality," Meghan McCain wrote on her Twitter page.
Meghan McCain appears holding an elephant - the symbol of the Republican party - with tape over its tusks.
Running for president, John McCain said he believed marriage should be between one man and one woman.
He reiterated that view through a spokeswoman Thursday.
"Senator McCain respects the views of members of his family. The senator chaired the effort to successfully pass Arizona Proposition 102, the Marriage Protection Amendment, and his opposition to gay marriage remains the same," Brooke Buchanan said.
The No H8 campaign arose in response to California's back-and-forth on same-sex marriage - first approved by the courts, then overturned by voters in a statewide referendum called Proposition 8. The issue is back in court now.
Bouska, a photographer, launched the site with Parshley "as a silent protest," they wrote.
It showcases pictures of Californians who oppose Proposition 8, they wrote when it launched nearly a year ago. It expanded to include celebrities and other supporters of same-sex marriage, all appearing with duct tape over their mouths and "No H8" painted on their cheeks.
Good for Cindy McCain. My respect level for her just increased.
I'm so glad to see prominent Republicans coming out in support of marriage equality. This isn't a partisan issue, it's about civil rights.
I'm no fan of the McCains, but good for Cindy and Meghan in taking this stand!
Cindy McCain for Pres in 2016!!
Cindy Deserves a lot of respect. Their family is one of the classiest in the political spotlight in years. Cheers to them for raising the bar.
Wow! I haven't thought much of Cindy McCain in the past, but I have to admit, I'm impressed. Bravo.
Wow, I'm impressed! Thank you Cindy McCain for standing up for marriage equality!
Don't mean any disrespect to Mz. McCain but can anyone credibly define just what useful purpose does homosexuality serve? The only two that come to mind is personal preference and personal lust. All knee jerk emotionalism aside If Homosexuality is a civil right as legislated from the bench then does it not also follow that any other personal preference in sex is also a civil right? Considering that this will have to be passed there is a great possibility that this comment will not be posted. Shame too because the points and the question happen to be honest ones.
What's the problem. If a dumb butt senator to be can pose nude what's wrong with Cindy McCain having an opinion. Or are republican wives supposed to get permission from the whole party before they can do anything.
Good for her. Just because her husband isn't very smart doesn't mean she can't come to the right conclusions on her own.
Wow, in an instant my entire opinion of this woman has changed!
the writing is on the wall. sooner or later the conservatives have to wake up to the fact that there are a lot more liberals then they can ever come up with in their own nightmares.
Excellent statement on her part
Smart Move Cindy! It's about time the GOP loosened it's grip on those outdated ideals.
Next, can someone please start convincing people that Stem Cell research is not a product of the Devil?
Brava to Mrs. McCain and her daughter for standing up for equality.
I guess bravo to McCain for, ummm, sticking to his views of hate and discrimination?
Let's see what nasty things Democrats can find to say about this story.
Awesome! Good for her!
I'm glad some of the McCain clan are not dragging their knuckles on the ground.
wow! very cool indeed...who would have thunk it... i'm sure sarah will have some dim witted reply to mrs. mccain's actions..but i'm pleasantly shocked!
CINDY MCCAIN JUST MOVED UP A NOTCH IN MY BOOK!!
What ever happened to the sanctity of the marriage institution? I'd like to see what John McCain has to say about this.
This only goes to show the extent of hypocricy of republicans and politicians in general. Their stand on issues is self-serving. No moral grounds what-so-ever.
My opinion of Cindy McCain just went up a couple of notches. Good for her.
Good for Cindy! The gay rights movement needs the support of straight people who speak out for equality, and especially of Republicans who, more often than not, use "family values" as a way to alienate and disenfranchise people while engaging in their own scandals. Sanctity of marriage, indeed. Thank you, Cindy and Meghan! Please keep it up, and hopefully more people will follow suit. Civil rights are never easily won.
Now folks the gop will put her to death on the cross !!
Good for her! Surprisingly, I know quite a few Republicans who support same-sex marriage. Many are 'socially liberal, economically conservative'.
WOW! I never thought I'd say this, but Cindy McCain...You Go Girl!
