The Americans with Disabilities Act has increased the power of the federal government over the states by mandating that every state prohibit discrimination against citizens with disabilities. This gives more power to the federal government because it does not give the states any power to vary from the national law.

Preemption gives more power to the federal government by allowing the federal government to get rid of a state law and replace it with a federal law. This gives the federal government ultimate supremacy and limits the states' power to waver in the law.

US v. Lopez gave more power to the state government when the Supreme Court decided that Congress could only have a say in channels, instruments, people, and things related to interstate commerce. This gives more power to the states by allowing them to individually monitor their state commerce.

Devolution gives more power to the state government by specifically taking powers from the national government and giving it to the states. This makes the states more powerful because they gain jurisdiction and the national government loses some.
