Oh! Good thing I listened to my own recommendation, because I sure learned something. I've probably been mixing up Madison and Hamilton, because Gutzman says that Madison did hold centralist views before ratification, but by the time he was President, he had come to appreciate the position for limited, enumerated rights, and vetoed bills that went against it.

That explains why there was no obvious reference to Madison in the latest 12 months of TWS. I'll look for a Hamilton reference instead. But the show linked definitely brings up the "intended decentralization, de facto centralization" story, and it's a good episode.
