WA: How Bad Is Barnett's Latest Polling?

I last covered Western Australian state polling in March, in an article called A New Species Of Strangeness In The West.  At that time, despite increasingly bad Newspolls for the Barnett Liberal government, there was a bizarre and very short-lived call to replace Opposition Leader Mark McGowan with former federal MP Stephen Smith.  Since then it is Barnett who has gone through the normal process of leadership speculation and challenge that strikes leaders who are actually polling badly.

It came to a head in mid-September when then Transport Minister Dean Nalder quit Cabinet and launched a leadership challenge, in which his proposal for a spill managed to get 15 votes out of 46 although there was almost no public support for him as leader (5.5% in ReachTEL) and a widespread perception that his challenge was hopeless from the start.  This would normally be the beginning of the end for an incumbent Premier, but the difference here is that if someone is going to throw Barnett under the bus, they will need to get a wriggle on.  It is just over four months til the election.
