Yes, I think you would have to go back to Jim Cairns to compare a more incompetent treasurer.
I remember seeing Cairns outside Prarhan Market in Melbourne on Saturday mornings alone trying to flog his book and trying to rope in anyone to talk to. He was a sad pathetic figure during and post-Whitlam.
Swan is completely incompetent for the job or treasurer and completely duplicitous. He craves the good opinion of commercial types, but he will never have it.
