An interesting article from Volokh-Conspiracy about Yale Law School Dean Heather Gerken. The article itself has many links to her other works and opinion. She has plenty of good thought process with respect to liberals adopting federalism as a permanent part of the progressive position rather than the current trendy version used to block Trump. She however, not unlike some on the right, tend to see the all too frequent opportunities to press her position at the national level when she knows the belong to the state or even local.
The problem she has in promoting federalism as a way to forward progressive thought by people 'voting with their feet' is, unfortunately the same problem communism has... their will be no successful progressivism until the last vestiges of liberty are wiped off the map.
