Over 80 Republicans have signed an amicus brief asking the Supreme Court to find a constitutional right to marriage for same-sex couples. Who are these extraordinarily supportive Republicans? They’re largely those who have served in top-level Republican National Committee (RNC) posts, the George W. Bush administration, Congress, or are GOP strategists. They also largely have little to lose, as they’re not running for re-election, with the exception of Congresswoman Ileana Ros-Lehtinen and Richard Hanna (image: bottom left and right).

But many had previously supported only so-called “traditional marriage,” and many also supported a constitutional amendment banning same-sex marriage, so the message to the Supreme Court is huge.

“Backers have been working for about three months on the list, which includes Republicans who have been wrestling for year on what position to take on the issue,” Politico reports:

AFER said the signers include “social and political conservatives, moderates, and libertarians from diverse religious, racial, regional, and philosophical backgrounds.”

Ken Mehlman, a board member of AFER who managed former President George W. Bush’s reelection campaign and personally secured many of the signatures, said in an email to POLITICO: “Ronald Reagan, our great conservative President, used to say, real change occurs around the kitchen table. This brief is reflective of real change occurring all across our country as families sit around kitchen tables, think about the value of family to their own lives and recognize these benefits should be available to all Americans.”

While the Supreme Court has received dozens if not over 100 amicus briefs on same-sex marriage for next month’s hearings, they will have little effect. This one, however, is different.

“Experts say that amicus briefs generally do not change Supreme Court justices’ minds,” the New York Times reports:

But on Monday some said that the Republican brief, written by Seth P. Waxman, a former solicitor general in the administration of President Bill Clinton, and Reginald Brown, who served in the Bush White House Counsel’s Office, might be an exception.

Tom Goldstein, publisher of Scotusblog, a Web site that analyzes Supreme Court cases, said the amicus filing “has the potential to break through and make a real difference.”

He added: “The person who is going to decide this case, if it’s going to be close, is going to be a conservative justice who respects traditional marriage but nonetheless is sympathetic to the claims that this is just another form of hatred. If you’re trying to persuade someone like that, you can’t persuade them from the perspective of gay rights advocacy.”
