No, it's different. Delegated to the states implies that someone else had the power and gave it to the states. That is not true. The states always had the power, and have had it since they formed, and it was not removed upon admission to the United States.

It's like saying France was delegated the power to enforce a national quarantine. That is simply not the case.

No, you are getting it backwards. The states predated the general government. The states delegated powers to the general government.
