Speedy,
No idea why they don't like him, I've only heard very good things about him on the line, but after the Super debacle when AIPA disgracefully and childishly tried to oust him with a very big campaign for another member by sending out strongly worded leaflets endorsing their guy and rubbishing IW, they lost my confidence there and then! It was a waste of funds/time and smelled of 'jobs for the boys.' Funnily enough since then, communication on real issues from AIPA has been scarce.....
Of course IW was then voted in overwhelimingly and look what he's achieved. Good on him and the reform group, they have my vote.
