As Jack M. Balkin, Yale Professor of Constitutional Law, points out on his blog Balkanization, "Unless you can demonstrate that under South Carolina law, the South Carolina Legislature, acting alone, speaks for the State, it would seem to me that the governor's consent is necessary.
Spending Clause jurisprudence requires that the state freely consent to conditional grants by the federal government. But not just any state official may give consent. The question of who is authorized to give consent to accept federal funding is a question of South Carolina state law, not federal law. Federal law can offer the states money to enforce federal mandates and even to pass legislation, but what it may not do is decide which state official is authorized to consent to federal grants that bind the state and its operations."
The last time South Carolina spurred a constitutional crisis, it did not end well for us or for the nation. (See American Civil War) Is this going to end the same way? Meantime, what happens to the people who need help?
Oh, I remember: the faith community and non-profits will step in to save the day.
