The thing is, he does actually seem to have been a very good local member. He was dreadful as opposition leader, but as "the local rep" in a single seat he was competent and conscientious.

If we hadn't just been shown exactly what that actually means - behold, the United States! - it might be more popular. But we have, and for all that Australians love a good bitch about politicians...we don't love it enough to burn the place down
Any given voter's choice, regardless of who they vote for or if they vote at all, is always a valid and correct one. There are no wrong answers. Even if the decision ends up being one they find they disagree with later on for Reasons.

Even if it could...voters are never wrong. Sometimes the choices of voters have unforeseen consequences, but as a voter exercising your rights you cannot make a wrong choice doing it. Whatever you picked is right.
