Republican presidential nominee John McCain said Tuesday that California voters, not judges, should decide who gets married in the state. Perhaps this simply states the obvious--the initiative to ban same-sex marriage will be on the November ballot. But it feels like a political mistake. In the recent past, McCain's advisors have suggested they see California as in play with a Schwarzenegger-style campaign -- that is, an approach that avoids talk of social issues and instead emphasizes fiscal issues and the importance of bipartisanship. By wading into this initiative, McCain, who never had much of a chance anyway in California (where polls show Obama would have won a California primary held on June 3, the originally scheduled date), is eschewing the Schwarzenegger approach. In fact, attempting to use the same-sex marriage issue in any way feels positively Rovian. In the process, McCain shows he's not serious about winning the state.
