Is there an expiry date for Australian politicians we don’t know about?

According to the latest Newspoll results released by The Australian, Prime Minister Malcolm Turnbull’s satisfaction rating has fallen to its lowest in five months, although the public continues to pin their hopes on the businessman if they had to choose between Turnbull and Bill Shorten.

Tuesday's results showed 41 percent of 1,815 Australians polled were dissatisfied with the way Turnbull was doing his job as PM, a slide from November, which saw 22 percent of respondents expressing their doubts.

Meanwhile, the Coalition’s primary vote remained at 43 percent -- similar to February polls -- which continues to be their lowest since Turnbull became prime minister. Labor polled at 35 percent, and Greens at 12 percent.

The Coalition also remained deadlocked with Labor at 50-50 when it came to two party preferred terms.

While no doubt a downer for Turnbull and the Coalition, the results have not surprised too many Australians or political pundits, who link Turnbull’s dismal poll numbers to his hesitancy to “walk the walk”.

“Turnbull and his embattled Treasurer, Scott Morrison, seem to be incapable of decision-making. The government is riven with division and drifting amid a sea of uncertainty on a number of policy fronts,” senior writer at The Australian Troy Bramston wrote just two days before the Newspoll results were released.

“They have not yet provided a compelling case for re-election. Where is the vision they promised?”

Former Secretary to the Treasurer John Stone in an opinion piece also pointed out Turnbull's failure to capitalise on the political capital he was well-endowed with when usurping the prime ministership almost six months ago.

"Rather than expend that capital by taking an axe to what was now his government's wasteful spending he has chosen instead, in John Howard's recent words, to 'dissipate it by sitting around and doing nothing'."

Then there’s the term “waffle”, frequently used to describe the current PM.

The March polls come off the back of a number of ‘bad days’ for the Coalition, including its failed efforts to slam Labor’s plans to limit negative gearing in Parliament, and the leak of a sensitive national security white paper to The Australian.

Meanwhile, the satisfaction rating for leader of the opposition Bill Shorten jumped to 30 percent, but when it came to the question about who would make the better PM, Turnbull beat the ALP leader 55-21 percent.
