Gay marriage advocates are touting the number of Republicans — more than 130 at the moment — who have signed an amicus brief urging the Supreme Court to overturn California’s popularly-approved ban on same-sex marriage. …

One notable thing about the brief is that the list of signers includes several top officials from the Romney presidential campaign. Mitt Romney strongly opposed gay marriage during the 2012 race. Signing the brief now in support of gay marriage are Beth Myers, perhaps Romney’s closest aide in the campaign; Ben Ginsberg, the campaign’s influential lawyer; David Kochel, the campaign’s main strategist in Iowa (where Romney worked hard to win the support of Republicans for whom traditional marriage is a key issue); Katie Biber, the campaign’s general counsel; Lee Rudofsky, the deputy general counsel; and Alex Lundry, a top tech official in the campaign. …

“The only surprise here is that Romney himself didn’t join them,” Bob vander Plaats, head of the social conservative group The Faimily Leader, told me in an email. “As you know, many conservatives did not trust Romney on marriage, life, and other social issues…Now, true colors are exposed by these leaders of his campaign…You can tell a lot about a person by who he chooses to surround himself with.”
