The Framers included the Supremacy Clause in the Constitution because they believed that the national government needed to have more power than the state governments had. They felt that the state governments had previously had too much power and that the country would be better off if the national government were more powerful.
First, the Framers felt that there would be no point in having a country if the federal government’s laws were not supreme. If the states could pass laws that would override the national laws, there would be no real sense in which the states were united. The Union would essentially just be a confederation in which all states were sovereign.
Hope this helped ;)
