We can't even find politicians who can understand, "The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people" but somehow we're supposed to expect them to understand all that gobbledygook?
The states "delegated" powers to the federal government, they didn't "abdicate" them.
As with any power that has been delegated, the entity that delegated those powers have the right to take them back when necessary.
