Iron Mike only Blind Right Wing Radical Freddie can see any bias in Kerry O'Brien- look back at his interview with Rudd and see if you can pick up any bias there. If you trace the demise of Rudd you could start at that interview.
I think there is more bias in a Womens Weekly puff piece or a News Corp article than a Tony Jones interview. The ABC remains the most independent of all media outlets and if you cant see this then maybe you should be watching Sunrise instead of Q&A or Lateline. I still find O'Brien and Jones interviews harder hitting on both sides than anything on commercial media.
