THE BURNED OVER DISTRICT

If The Gay will be the rock upon which the Republican Party shatters itself as a national party.

As the case against equal rights for gay families gets harder and harder to argue on any nonreligious or legal grounds, no wonder so many conservatives are dropping the cause. And if Fox News and Rick Warren won’t lead the charge on same-sex marriage, who on the national stage will take their place? The only enthusiastic contenders seem to be Republicans contemplating presidential runs in 2012. As Rich Tafel, the former president of the gay Log Cabin Republicans, pointed out to me last week, what Iowa giveth to the Democrats, Iowa taketh away from his own party. As the first stop in the primary process, the Iowa caucuses provided a crucial boost to Barack Obama’s victorious and inclusive Democratic campaign in 2008. But on the G.O.P. side, the caucuses tilt toward the exclusionary hard right.

In 2008, 60 percent of Iowa’s Republican caucus voters were evangelical Christians. Mike Huckabee won. That’s the hurdle facing the party’s contenders in 2012, which is why Romney, Palin and Gingrich are now all more vehement anti-same-sex-marriage activists than Rick Warren. Palin even broke with John McCain on the issue during their campaign, supporting the federal marriage amendment that he rejects. This month, even as the father of Palin’s out-of-wedlock grandson challenged her own family values and veracity, she nominated as Alaskan attorney general a man who has called gay people “degenerates.” Such homophobia didn’t even play in Alaska — the State Legislature voted the nominee down — and will doom Republicans like Palin in national elections.

One G.O.P. politician who understands this is the McCain-Palin 2008 campaign strategist, Steve Schmidt, who on Friday urged his party to join him in endorsing same-sex marriage. Another is Jon Huntsman Jr., the governor of Utah, who in February endorsed civil unions for gay couples, a position seemingly indistinguishable from Obama’s. Huntsman is not some left-coast Hollywood Republican. He’s a Mormon presiding over what Gallup ranks as the reddest state in the country.

Heh indeed! To see the party founded on the principle of civil rights destroy itself trying to deny civil rights.
