No, it isn't surprising, but I'm honestly wondering if they actually expect any political benefit from this outside of hardcore climate change deniers. The public are sick of the status quo, and Labor extended an olive branch of bipartisanship when the Finkel Review was released - some may say it was possibly cynical and opportunistic, but after this, Labor can easily shrug their shoulders and say "hey, don't look at us, we supported the review's measures including the CET, but the government won't get its act together because the right-wing loonies have Turnbull dancing to their tune. Vote Labor in at the next election, though, and we'll fix all your energy woes, because this government obviously can't!"
Nine more newspolls to go before the line Turnbull set to justify outing Abbot is passed. The status quo is untenable, but there's no way the government can turn this around barring a catastrophic error on Labor's part or a huge incident that plays to the Coalition's "strengths" politically.
