The 2012 campaign of President Barack Obama has launched a Facebook ad highlighting the president's support for all married couples.

The ad states: “President Obama supports equal rights for all married couples: gay, lesbian and straight. Show him he's not alone – add your name now.”

The campaign's title – Respect for All Marriages – is suggestive of the language used in a proposed bill that would repeal the Defense of Marriage Act (DOMA), the 1996 law that forbids federal agencies from recognizing the legal marriages of gay and lesbian couples. New York Congressman Jerrold Nadler's bill is titled The Respect for Marriage Act.

President Obama has endorsed repeal of DOMA.

And while the president has stopped short of endorsing gay marriage – he says he supports civil unions for gay couples and is “evolving” on marriage – the Facebook campaign appears to put the president within striking distance of endorsing full marriage.

In blogging about the ad, John Aravosis at Americablog.com noted it was incorrect to conclude that the president supports marriage equality.

“What's actually going on is that the Obama campaign, and [the] White House, have been trying to pull the wool over the community's eyes with a little bit of rhetorical trickery. The president is for equal rights for all couples, gay and straight, they keep telling us. And the proof they use is that he's for repealing DOMA (and that Facebook ad lands on a page about DOMA). What they don't say is that the only way to get those equal rights is for us to get married, and the president isn't for that.”

“So, the president says he supports equal rights for all married couples, and refers to gay couples as married in the ad, even though he opposes our marriages, which will stop us from getting the very equal rights he claims to support,” Aravosis wrote.

“Set your watches folks, and count the number of seconds before this little snafu gets retracted,” he added.
