A federal judge has overturned California's ban on same sex marriage, passed by 52% of the state's voters two years ago. Supporters have already appealed. The case will be in the courts for years and could be overturned, but it's still a landmark ruling, since homosexuality was illegal in some states just 10 years ago. It could be a political landmark, too, if some voters see it as another federal intrusion like the overturning of Arizona's immigration law and the requirements of healthcare reform. We look at the legal implications of yesterday's decision and the politics.
