Labor leader attacks carbon tax I am told by readers that WA Opposition Leader Mark McGowan has broken ranks with other Labor leaders to denounce the carbon tax. Surprisingly, the only reference anyway I can find to this important news - which the Coalition will surely exploit heavily in politics - is this item from Jo Nova: I saw on the ABC news tonight that Mark McGowan announced that he doesn't like the Carbon Tax. He's the West Australian state opposition leader and there are just four weeks left before the State election. Strangely I can find no story, no news headline to confirm this.
