Diving right in here.
At one point, early on, the Supreme Court and Constitution were not intended to dominate law in individual states.
The Federalists began to change this idea a bit. A lot of state constitutions were changed relatively quickly to fall in line with the big one. I find Madison (and Jefferson) to be extremely interesting in this particular respect. From what I've read, he did about 180 degree turn.
It has been along time since I delved into the Federalist Papers but I think the quote has to do with realigning the states constitutions under the federal constitution as supreme law.
That probably sounds weird at first glance but they were intent on learning from other nations mistakes. I'd lay odds on this one. They were talking about centralizing certain authority primarily international trade and military. (scratch, scratch,...I reckon).
Remember what happened after the civil war? Lincoln took this a leap forward.
I do NOT think they envisioned anything like the Patriot Act.
