David Weigel says that "Politically, I suppose this is bad news for the Democrats, but not nearly as much as in 2004. For one, it's not coming out of a candidate's home state." Tom Maguire, meanwhile, asserts that the California Supreme Court may have done the GOP "favor." As I've been through before, though, while I know I'm supposed to see 2004 results in which Bush underperformed structural models as proof of Karl Rove's strategic super-genius the allegedly large effects of gay and lesbian marriage on the 2004 election have been greatly overstated. And needless to say, predictions about how the New Jersey court's ruling were supposed to have a major impact on the 2006 elections will vanish down the memory hole.
I don't really find this surprising. People overstate the extent to which people vote on social issues, and people who get outraged by decisions permitting gays and lesbians in other states to get married are overwhelmingly likely to be Republican voters anyway. I don't think that the decision today will have any significant impact on the 2008 elections. It may increase turnout in California, but since the state isn't in play it doesn't really matter.
On a final point, Weigel over optimistically says that "John McCain voted against the Federal Marriage Amendment: He can't demagogue this, and he won't." Yeah, just like how his alleged "federalist" opposition to Roe stops him from supporting every piece of federal abortion legislation to come down the pike. I don't know what McCain will do but I am sure that an alleged commitment to "federalist" principles won't stop him from doing anything.
