You've read about the conservative version, whether fact or fiction; now try the liberal one.

  UPDATE: Amusingly, back in 2005, I wrote about how you could imagine a version of the "constitution in exile" meme that treated the "Constitution in 2020" conference as important to the liberal version of the "movement." The imaginary critique included this paragragph:

Restoring the liberal Constutitution in Exile has become an increasingly dominant theme of progressive legal thinkers. For example, a collection of some of the nation's most prominent progressive legal minds (including Cass Sunstein) will be meeting at Yale Law School in the spring to develop "a shared vision of what, at least broadly speaking, that Constitution in Exile is, so that we can support and work for its realization." A website and blog set up for the conference reveals the agenda. For example, Bruce Ackerman sets as one of the more modest items on the agenda to "[r]oot out the federalism decisions since Lopez, and return to the status quo, circa 1994. Root all of them out, not some of them." His more "transformative" agenda would include "overrul[ing the] Slaughterhouse [cases] and mak[ing] the [Privileges and Immunities] Clause the basis for fundamental positive rights of citizenship." Other scholars at the conference urge a new Constitution entirely. One scholar urges that the Constitution must be reconceived to serve "a basic purpose: the protection of human dignity." Another contends that the law must "revisit both the 14/19th amendments and the general welfare clauses so as to take on the deep inequalities of the contemporary social order inside the United States, to reconceive the meaning of equality."
