Before someone drops the Grant v. Lee (1865) reference hear me out.
A lot of states were upset by the No Child Left Behind unfunded mandates. One state (Utah) stood up to the Feds and refused the money and the strings with it which was apparently their right under South Dakota v Dole. Utah got slapped down via a lawsuit so I guess the states do NOT have a right to refuse legislation by pursestrings despite what SCOTUS said. Now they are seeing the same thing with UHC and 13 states are filing suit and they will be slapped down too by the judiciary. That doesn’t even count states like mine (Arizona) that are considering not filing suits because they can’t afford to fight a sure-fire loss.
Now let’s combine that with the unwillingness of the Federal government to combat illegal immigration and refusal to pay their legally mandated bills to the states. Even California’s attitude of turning a blind eye to the problem is being tested when “the illegals are taking our jobs” and we are at a 10-20% unemployment rate depending on how you measure it. If I were a governor of a border state I would put the national guard on the border myself or start billing the Republic of Mexico directly for caring for their nationals and let the Feds deal with the international crisis. I also would challenge the validity of Wong Kim Ark in SCOTUS contending that in Ark, his parents were LEGAL residents. Probably because these efforts are destined for failure, California, Arizona, New Mexico and Texas jus complain about money, the border (non)fence and anchor babies.
The states did ban together to call for a Constitutional Convention in 1900-1910 which resulted in the 17th Amendment before 3/4 of the states voted for a Convention so they are not powerless. And just yesterday, Arizona pulled out the pre-Civil War theory of state nullification when it declared that handguns manufactured and used in the sovereign state of Arizona were exempt from federal regulation. So when all of these legal challenges to federal powers are dismissed, will the states get together and call for a Constitutional Convention? If so, will the Feds back down like they did in 1910? Is it just possible that a wacky-ass state will actually rebel like calling out the National Guard and challenging the Feds to enforce their laws? Or will it all flicker away once football season starts?
