Answer: the power of the national government
Step-by-step explanation:
The Constitution of the United States gives the Federal Government power over the states by making Federal law absolute such that Congress, the President and the Supreme Court are very powerful.
Before the Constitution was designed, this was not the case as states reigned supreme. Some people preferred this style of government such that they opposed the ratification of the New Constitution because they said that the national government would simply be too powerful.
