Bribe Based Federalism

One of the most common means by which the federal government secures state compliance with federal policy is by linking federal funds to state policy actions. The "No Child Left Behind Act" is one such example. The national drinking age and DUI limit and speed limits are other examples. What happens when the federal government then fails to deliver on the bribe that secured a change in state policy? The 6th Circuit addresses that question today in a way favorable to the states.
