How dare you! Bob Hawke studied Arts/Law at the University of Western Australia (God Bless UWA!). He then went on to study a Bachelor of Letters in Oxford, via a Rhodes Scholarship. Bob Hawke did begin a PhD at ANU, but abandoned that in favour of a position in the ACTU.
To quote Wikipedia, "His academic achievements were probably outweighed by the notoriety he achieved as the holder of a world record for the fastest consumption of beer." And that my friends, is the measure of a politician. I can assure you, George W. Bush is a mighty fine politician by that particular standard.
