There is a very good article in this Sunday's New York Times (which does make it rather long) entitled "After the Imperial Presidency".
Covers many interesting topics involving the workings of the Office of the President and Congress (in particular the Senate). Also talks a bit about Sen. McCain and POTUS to be Obama.
