The constitution makes a more perfect union because everyone is treated as equals. No one is above anyone else, so conflicts won’t occur. Even the president has to pay taxes. The constitution also protects individual rights in the bill of rights that no one can take away.
The constitution unites the states because everyone has a set of rules to follow. Before the constitution was created, Britain was a monarchy, and the colonists didn’t like having no say in government. With a monarch, everyone is subject to the will of the king, and no one has a set of laws to follow. In this constitution, everyone has a set of specific laws to follow. Therefore, everyone is united.
