He says he realized it “fairly recently,” in Marc Ambinder’s words, which has Tammy Bruce chuckling on Twitter. Honestly, I thought the guy came out years ago. Remember when Bill Maher talked about the rumors surrounding him on Larry King’s show — back in 2006? I guess you were the last to know, Ken.

He’s doing this now, it seems, because he wants to drum up publicity for the cause of gay marriage and figures that “Republican whom everyone thought was gay actually is gay” headlines will do the trick. Could be, although Ambinder’s careful to remind readers of the sort of social con initiatives that the GOP pushed during Mehlman’s RNC tenure. That won’t endear him to gay activists, and his newly public identity won’t endear him to social cons. Maybe he should have just worked for gay marriage like Ted Olson and kept his orientation private?

Privately, in off-the-record conversations with this reporter over the years, Mehlman voiced support for civil unions and told of how, in private discussions with senior Republican officials, he beat back efforts to attack same-sex marriage. He insisted, too, that President Bush “was no homophobe.” He often wondered why gay voters never formed common cause with Republican opponents of Islamic jihad, which he called “the greatest anti-gay force in the world right now.”

Mehlman’s leadership positions in the GOP came at a time when the party was stepping up its anti-gay activities — such as the distribution in West Virginia in 2006 of literature linking homosexuality to atheism, or the less-than-subtle, coded language in the party’s platform (“Attempts to redefine marriage in a single state or city could have serious consequences throughout the country…”). Mehlman said at the time that he could not, as an individual Republican, go against the party consensus. He was aware that Karl Rove, President Bush’s chief strategic adviser, had been working with Republicans to make sure that anti-gay initiatives and referenda would appear on November ballots in 2004 and 2006 to help Republicans.

Mehlman acknowledges that if he had publicly declared his sexuality sooner, he might have played a role in keeping the party from pushing an anti-gay agenda.

“It’s a legitimate question and one I understand,” Mehlman said. “I can’t change the fact that I wasn’t in this place personally when I was in politics, and I genuinely regret that. It was very hard, personally.” He asks of those who doubt his sincerity: “If they can’t offer support, at least offer understanding.”

I couldn’t care less either way, but with all the buzz lately about new conservative support for gays — here’s the latest surreal episode in the Coulter/Farah HomoCon saga, incidentally — this is a bracing reminder that an openly gay RNC chief probably would still be a problem. Or would it?
