Pauline Hanson is the only one, what?
Well, she's the only politician who has gotten away with deliberately defrauding the Commonwealth over the number of members in her political party. The Electoral Commission said there had be at least 500. Pauline had three (herself and the two Davids). Tone Rabbit fixed her little red wagon over that one. John Howard got her out of prison because it was politically expedient to do so.
Well, she's the only politician who has taken the Australian voters for all the money she can, by nominating to run in multiple Federal and State elections with absolutely no chance of winning but sufficient to make quite a tidy profit for herself.
Well, she's the only leader of a political party that keeps getting dud candidates into the Senate to see them turfed out again when they transgress the Constitution or get pissed off with her.
Well, she's the only leader of a political party that appears intent on screwing the Parliament by not declaring gifts and so on when she's received them from voters.
Well, she's the only politician who appears to hate Asians/Muslims/Immigrants and not care what damage she does to Australia or the individuals concerned.
Overall, she appeals to the lowest common denominator in Australian society unfortunately. She spouts hatred towards anybody who doesn't fit her definition of an "Australian". If they worship a different god, if they look different, if they act different, she dislikes them intensely and plays on the ignorant hatred of them to get votes. Not a good look at all IMO. Not a great look for Australian society. Tsk, tsk.
