The relationship between the federal government and the states is a complicated one. States, at times, may want to make policy choices that differ from the ones the federal government makes. Elaborate on this topic that takes a position on which form of federalism is the most workable strategy, whether you believe states should have more or less autonomy in making laws that apply to the people of the states, and if you think there should be a strict separation between states' authorities and those of the federal government, or not. Make sure to cite examples of current challenges in the issue area of federalism and any Supreme Court decisions that you're aware of in which the Supreme Court has taken a stance on issues of federalism.
