The Politically Incorrect Guide to the Constitution by Kevin R.C. Gutzman, J.D., Ph.D., Regnery Publishing, Washington D.C., 2007. This is a fascinating read and sure explains a lot.

One of the things he shows very convincingly is how, from almost the beginning, it has been subverted by activist judges, beginning with John Marshall.
