The Lewis and Clark Law Review has published a most interesting symposium entitled: "Federalism After Gonzales v. Raich." They have also put the symposium articles online for free download. Here are links to all the articles, though if you only have limited time, Pushaw's neo-federalist framework is quite sensible, and well worth reading:

Raich and Judicial Conservatism at the Close of the Rehnquist Court by Eric R. Claeys
