Supporters of gay marriage in California have now taken their case against that state's marriage amendment to federal court. At issue is California's Proposition 8, in which voters in 2008 voted to define marriage as the union of one man and one woman.
Given that this is now a federal case, it will start out in district court, then - no matter who wins or loses - will be appealed to the (liberal) Ninth Circuit Court of Appeals, and then to the US Supreme Court.
In the end, it's not just California's Prop 8 that's at issue, but it will be the definition of marriage in all fifty states. In other words, what the pro-gay marriage crowd is looking for is the gay marriage equivalent of Roe vs. Wade, where the Supreme Court steps in and sweeps aside citizen passed laws all across the country and short circuits the political process all together.
