This is an encouraging ruling but watch out for the Dems to devise a plan B to circumvent the decision, if the USSC should uphold it. They are not going to give up easily and will happily skirt the law to do it.
I expect the Obama administration to attempt to drag out this decision anyway that they can. I guess that will mean going for a full court in the appeals decision and then on to the Supreme court, hoping to drag it out until after the election next year.
