Those are general poll numbers amongst the general population not members. Watts is the most popular amongst the general public whereas Wilkinson and De Jong maybe less so with the general public but far more amongst the committed members. Todd Stone cannot be ruled out and Michael Lee does well amongst younger voters and signed up many new ones. Actually I expect this to take at least three ballots and the only prediction I will make is Sam Sullivan is knocked off after the first ballot.
Watts is at 30% amongst the Liberal Party Leadership electorate, not the population at large. It doesn’t say anything about her leading amongst the general population, just the leadership electorate.
