Answer: One could correctly argue that it is a violation because the states have different populations and should have proportional votes.
Step-by-step explanation:
Popular sovereignty is a concept based on the idea that government is meant to benefit its citizens, and states that the only source of governmental power is the people.
It´s reasonable to say that each State having one vote is a breach in popular sovereignty as the states´populations differ and ought to have equal representation regardless.
The popular sovereignty principle would later become a main idea of the United States Constitution.
