Goodbye Supply Side?

National Review's Kevin Williamson has begun a worthwhile debate with his recent "Goodbye Supply Side." The New York Times' Ross Douthat reacted positively, as has supply-side critic Jonathan Chait at The New Republic.

For the defense, a particularly good analysis by "Econoclasts" author Brian Domitrovic. Also weighing in, Cato's Dan Mitchell and columnist Ross Kaminsky.
