As you've no doubt heard, California's Supreme Court overturned the state law banning same-sex marriage today. Culture Warriors have already swooped into action ginning up fear of this Grave Threat to Marriage, as was inevitable. What remains to be seen is how campaigns go about capitalizing on the ruling, and how religious constituencies respond.

Dan Gilgoff opines on the God-o-meter:

The [Federal Marriage] amendment has gone nowhere in the years since then [2004]. But supporting it and roughly a dozen similar state-level constitutional amendments became the rallying cry for Christian conservatives who played a huge role in Bush's reelection. The GOP's evangelical grassroots have been unwilling to play a similar role for McCain for a litany of reasons. Will McCain seize this moment to try to change all that, reverting more to a Karl Rove style get-out-the-base strategy, or will he stick to running a much more centrist campaign by hedging on support for a constitutional amendment? This is a moment of truth.

A bigger question is whether such a strategy would still work, or whether the issue has lost salience vis-a-vis common good issues among religious conservatives who turned out in opposition in 2004. Stay tuned. This is a moment of truth alright, as much for the voters as for the candidates.
