Gay-rights activists are upset over a McCain robo-call campaign attacking Romney. Here's the relevant portion of the call:

"Mitt Romney thinks he can fool us. He supported abortion on demand, even allowed a law mandating taxpayer-funding for abortion. He says he changed his mind, but he still hasn't changed the law. He told gay organizers in Massachusetts he would be a stronger advocate for special rights than even Ted Kennedy. Now, it's something different."

That last part is what has so angered gay-rights groups, and, according to Marc Ambinder, the campaign has pulled it as a result.
