Quite possible, it will be interesting to see how Labor, refocus and regain some of the middle ground.
I saw a bit of Christine Milne on the news, she appeared a bit like a ship without a rudder also.
My quess is they are going to have to wait untill Abbott makes a stuff up, or public sentiment turns against him. The elections in Tasmania and W.A, may give some indication.
Abbott has them over a barrell with the Carbon tax, they either have to stick with their principles and support an unpopular tax or back down and look silly. They will need some fancy footwork to come out of this issue looking good.
