First there's the no-take-backsees argument, most eloquently and passive-aggressively expressed by Ramesh Ponnuru at National Review:
Stanley Kurtz writes, “Did anyone on any part of the political spectrum ever actually believe that Obama opposed gay marriage?” My guess is that the answer is yes, millions of people heard him and assumed he was telling the truth. That is, after all, why he said what he did.Ponnuru's cute when he plays dumb, but I'm sure most sentient creatures knew that Obama defending DOMA was like Republican presidents sucking up to unions -- something politicans have to do until they can get away with doing what they really want.
Another category of good news is all the fist-shaking assertions that Obama will pay for courting the gay. Mike Huckabee declares it may "destroy" Obama; Law Riot, incensed that Obama has "unilaterally decided what is constitutional and what is not," says it "could hurt Obama deeply come next year’s election"; "This is going to come back to haunt him" and "may come back to bite him in the ass," snarl the dead butch buckos at Flopping Aces; etc.
This sort of thing actually revives my optimism -- because these yahoos assert that most Americans hate homosexuals as much as they do as confidently as they assert that most Americans are with them on everything else. Since they're wrong about gays, it may be that they're full of shit about the rest of it, too. What a cheering thought!
Extra asshole points to Orin Kerr in a wonderfully weaselly Obama-vs.-our-sacred-Constitution post: "Now, I wouldn’t in a million years compare torture and wiretapping with gay rights," he says. "Obviously, the subject matter is totally and completely different. But..." Yeah, okay buddy.
(Graphic from one of the greatest cartoons of all time, John Holmstrom's "Bosko's Perfect Day.")
UPDATE. In case you were inclined to be taken in by Kerr's pretense, be advised that he's been seconded by Megan McArdle. I rest my case!
UPDATE. Doghouse Riley in comments: "I'm busy calculating the ergs of concern McArdle-Galt put out over Bush's signing-statement frenzy. Back in a minute." He has yet to return. Conservatives generally keep Constitutional concerns up their sleeves, and only produce them when they're holding a losing hand. See Party, Tea.
