1. No same-sex legal marriages can take place in CA right now. There is a stay which will probably remain in place as this thing goes through the 9th Circuit and on to the Supremes. This could take years.
2. The US has not legalized gay marriage.
3. There is no guarantee of what will happen in the Supreme Court (because of the purpose of the 9th Circuit, that should be no problem), although yesterday's ruling was extremely, extremely cleverly reasoned and incredibly legally sound. It's a remarkably strong document.
4. DOMA is still on the books.
5. Other than momentum and hope, today is exactly like yesterday.
