I think it's important to point out that we have an established process for dealing with laws in this country, as well as judicial precedent. In the case of the consitutionality of laws that are passed on the state and federal level, the usual procedure is for the courts NOT to issue opinions until AFTER the laws have been passed and until AFTER someone has experienced some particular action which aggrieves him/her.
(Florida is somewhat an exception from this sequence in that the Florida Supreme Court is empowered to issue "advisory opinions" about laws that haven't yet been passed and adopted).
Thus, what the Supreme Court found, in the suit brought on behalf of Indiana citizens to challenge the requirement of a picture I.D. to vote, was that no individual had been harmed. Now somebody has (the 12 nuns) and we expect another suit with more likelihood of having an effect.
But, the real problem lies with legislators who think nothing of passing un-constitutional laws in the expectation that the courts will straighten them out.
