I generally support Albo and still give him 7/10 for his leadership overall.
That said, I agree that going on that interview and acting like a dill were unforced errors. By doing the melon thing he alienated a lot of women and young people in general, who don't accept sexist behaviour.
I would say that it seemed out of character, or at least out of character for his public persona and history. Personally I'm happy to write it off as a silly mistake, which we all do on occasion, until or unless he does something similar.
However I'd also point out the truly horrific shit that Pauline posts and defends. If Albo farted in the cathedral, Pauline blew the place up. As for the other leader of the opposition, he hasn't got an original idea and seems to think being a one nation copy will work for the LNP, which leaves Labor as the only party anywhere near the centre, which like it or not is where most voters sit.
