Thorfinn - Vote the Bastards Out. A detailed, lucid post covering many of the reasons why Australia needs to vote out the Liberal party and John Howard with it.
While I'm at it, you should confirm your enrolment. If you have moved since the last Federal election but you have not updated your details, there is a good chance you will need to re-enrol (they seem to have done a bit of a purge recently). The closing date for re-enrolment is Tuesday, September 7th. So don't wait.
Update: Vote the Bastards Out makes reference to The Lyons Forum, which makes for interesting reading.
