You know my theory that politics should run on a similar system to jury duty, i.e. all adults over 18 get called up to act as a minister for a six month period. So you'd get a letter in the mail stating "Joe Bloggs, you are hereby the Federal Minister for Education from 1 July - 31 December, 2008. Please present at Parliament House Canberra on 30 June."
Sure there is a certain percentage of the population who is illiterate, psycopathic, mentally unstable but surely we can't do any worse.
