Tony Abbott’s personal approval rating has collapsed amongst voters and last week’s health debate appears to have played a significant role, a new Essential Research poll shows.

This week’s Essential Report shows a recent spike in support for Labor disappearing, with its 2PP lead softening back to levels of early March at 54-46 (-2%/+2%), on the back of a 2% fall in the primary vote for both sides and a similar rise for the Greens.

Kevin Rudd has failed to lift his approval ratings back to the highs of 2009, but has maintained his approval level with voters since Essential’s previous approval question on 22 February, with a 53%/36% approval/disapproval rating.

Tony Abbott, however, has seen a substantial reversal in approval. While his approval ratings had lifted in February, he has now more than reversed that, with a 33%/50% rating compared to 45%/36% in February.

The fall is across the board, but particularly among Labor voters. In February, Abbott had scored comparatively well with Labor voters, with a 28%/58% rating, but that has sunk to 16%/73%.  Coalition voters have also cooled toward Abbott, with a 7% fall and increase in his approval/disapproval numbers. It fell among both male and female voters — Abbott now has the approval of less than one-third of female voters.

But Coalition strategists will be concerned about the significant fall among voters over 50-years-old, where Abbott’s approval fell from around 60% to 40%. Given older voters are far more focused on health issues than younger voters, this suggests Abbott’s poor performance in last week’s health debate may have inflicted some damage on him.

The Government was criticised in the commentariat for giving Abbott, a better debater than the Prime Minister, equal billing with Rudd, but the Government strategy of keeping attention focused on health may well have paid off by putting the spotlight on Abbott’s obstructionism and lack of an alternative plan. Essential found that Labor has an overall advantage of 45-25% on the issue of who will best deliver health care — although Abbott’s personal rating on that question is less dire — Rudd only leads him by 45-29%, perhaps suggesting voters don’t look as negatively on Abbott’s stint as health minister as negatively as Labor would like them to.

Essential also explored how voters felt about the Government’s stimulus package and their overall economic confidence. Voters are less concerned about they or their family losing their jobs than at any time since the GFC, and 54% expect economic conditions to improve, in contrast to only 19% who expect them to worsen.

That confidence has fed through into voters’ views on the stimulus package. While there remains strong support for all elements of the stimulus package except the insulation program (which was the least-liked element of the program back in February as well), more than half of voters now want the Government to address the budget deficit and curb spending, compared to 34% who want to see more support for economic recovery.

After Easter and the school holidays, the political debate will begin to concentrate on economics and the looming Budget. The Government still faces the challenge of curbing spending growth without the sort of savage cuts that might endanger the transition from public-supported to private demand-driven growth. Essential’s poll suggests voters have already made up their minds that the time has come for normal economic management to resume.

It will be up to the Coalition’s revamped economic team of Joe Hockey and Andrew Robb to exploit that.
