The underlying assumption here is that there was already some sort of union in plce before the Constitution existed, but that it could stand some improvement. To understand this, take a look at the existing government under the Articles of Confederation. In doing your research, ask how the national government under the Articles was weaker than the government to be established under the Constitution.
