Things have not changed much....

"On hawkish foreign policy, on aggrandizing militarism and the military -industrial complex, on crushing civil liberties and granting unchecked powers to the police, on aggrandizing executive power and privilege-in short, on the major problems of our time, the Conservatives and Liberals are in broad agreement...and so now we face an America ruled alternately by scarcely differentiated conservative and liberal wings of the same state-corporatist system." -Murray Rothbard, The Betrayal of the American Right

The book was written in 1973, that quote in a 1991 revision.

Considering that the last two presidents, with significant bipartisan support, have both passed the Patriot Act and started or perpetuated pointless military actions, I'd say Rothbard pretty well nailed this one.
