To my understanding, Mitch McConnell’s sexual orientation has been rather an open secret in the Kentucky political establishment. I tend to think that if gay Republicans maintain what amounts to a civilized stance on gay issues, then they deserve their privacy. If they dedicate their careers to making things really difficult for other gays and lesbians, then I don’t have a lot of sympathy. McConnell’s position on these questions isn’t as bad as some (he’s never, as far as I know, demagogued the issue), but it’s not good, either.
All that said, the ads linked above are pretty goddamn ugly. They do not in any manner or fashion put the drive for GLBT civil rights in a good light; in fact, just the opposite. While pointing out hypocrisy on this issue is always rather awkward, it can be done in a way that doesn’t rely on homophobia to make the point. I certainly hope that Bruce Lunsford had nothing to do with the ads. There’s no immediate reason to think that he did; AFSCME sponsored the radio version.
