I think it demonstrates the extent to which this fucking blindsided him.
It really is something for a leader to simply go "I have no idea; why don't you guys decide at some point".
Given how he was MIA on the Bishop thing, he really seems like he doesn't want to be PM anymore.
It would be quite funny if he wasn't the PM, it's now just getting sad. At this point, flipping a coin would provide far better leadership, Abbott seems to get it wrong every time. Abbott looks like a guy who desperately wanted to be PM, but didn't know why. A bit like Shorten really.
I really believe Abbott and his backers though it would be easy, 3-4 terms to enact their maddness. Backed by a pliant media they could disappear into the background and not have to answer any questions. Remember at the start of his term, Abbott just disappeared! Coupled with the fact the he just couldn't stop being the opposition attack dog all we have now is a small angry man with a ridiculous comb-over.
Say what you will about Howard, but he had political nous and was very good at reading the mood of the electorate and at time bending it to his will. Howard was also surrounded by many canny operators and managed to win probably 2 elections by all right he shouldn't have. The current clowns are the leftovers from the Howard era, now in charge and with no idea.
