Funny then that it was by states the Constituion was ratified, not a general vote of the whole people, each state had to give it's permission to have those "perogatives" transferred to the National government. Most of them had already been transferred by the Ariticles of Confederation, but the national government under the Articles was too weak to properly carry out it's duties. The main weakness was it's inability to generate it's own revenues, and to take certain actions without express permission from the states. The national government wasn't really sovereign, even in it's areas of responsibility, and that was what the Constitution was written to correct. Of course it was still strictly limited to action in only those areas ceded to it by the states, but nobody pays any attention these days to that part of the document written by those dead white mean.
The Constitution was ratified in special conventions, not by the state legislatures.
The people are the sovereigns of the country, not the states.This is stated explicitly in four seminal court cases:
Chisholm v Georgia, 1793
Martin v. Hunters' Lessee, 1816
Mccullough v. Maryland, 1819
Coihen v. Virginia, 1821
