My guess is that some of these states will attempt to pass nullification laws--claiming that the Supreme Court has overstepped its boundaries. But to my knowledge, no state has ever successfully been able to maintain a nullification law to override the Supreme Court.<quoted text>
I don't know if it is so much of a race, as a guarantee. I think if given enough time a majority of the States will adopt a form of same sex union, be it Marriage, or a Civil Union with the same benefits.
Now, the other side of the coin is that the SCOTUS makes another sweeping decision forcing all states into compliance, forcing the adoption of same sex marriage. This will cause 31 States which have adopted Constitutional Amendments to strictly define marriage as one man and one woman to feel disenfranchised, at a time when many feel that was as it is. A majority of the country is quite ticked off at Washington DC, and there is a push towards State right's and returning to the republican form of government our founders gave us. This could just be the straw that breaks the proverbial camels back.
The lawmakers here in TN are trying to pass a law that would allow local and state police to arrest and charge federal agents who might attempt to enforce any gun laws that TN lawmakers believes violates the Constitution. I say, "good luck with that".
I don't think you'll see a rush by all states to fight a sweeping Supreme Court decision.
Like I said earlier; too many states are headed towards legalizing same-sex marriage. Lawmakers in many of these states will take it as a welcome opportunity to have the decision made by someone else. They don't want to piss off those who support same-sex marriage and they don't want to piss off those who don't support it. So they'll just shrug their shoulders and say to their constituents, "It's out of our hands."
