Drover's dog comes immediately to mind, but it has got to the stage, (if you are convinced we need a change), of either voting Liberal/ Nationals or the Independant's, or Drovers donkey, (and look at where we are because of them), or Bob Brown and his team from Looney Tunes, (who unfortunately some misguided souls saw as somehow "keeping the bastards honest"). (Apologies to any remaining Democrats still alive or who care to remember). Or The Labor Party who are the bane of most problems.
That's all folks!
