Plenty of standing, the federal gov has been stomping on 10th amendment rights for decades.

The current Federal government as it stands today is an illegal usurpation of State's rights, and I'm talking about what has transpired SINCE the Civil War. Campaign Finance Reform, not allowing us to drill for our own oil, non-enforcement of our border and immigration laws, and Eminent Domain (and that's just under King Jorge) are examples of this even before all this federally sanctioned redistribution of wealth (legalized theft).
