The End of "Popular Constitutionalism"?

There aren't that many book reviews that finish off an intellectual movement, but Scot Powe's review of Larry Kramer's The People Themselves:  Popular Constitutionalism and Judicial Review (Oxford University Press, 2004) in the current Texas Law Review 83 (February 2005):  855-896, does just that.  The criticisms are so devastating--both as to the astonishing historical omissions, and the argumentative non-sequiturs at the core of the book--as to make it puzzling how the theory got as far as it did.  Comments are open, for those who are familiar both with the Kramer book (or his earlier articles on the subject) and the Powe review.  Do I overstate the import of the criticisms?  Is the corpse of popular constitutionalism still breathing?  No anonymous postings, of course.
