Labor is back in an election-winning position, according to a national poll that shows the government’s more friendly budget measures have faded from public memory.

The Coalition has been dragged back behind Labor in three states and nationally by six points, Morgan Poll revealed.

The government’s budget released early in May was seen as benefiting small business owners but over time analysis has revealed it will end up costing low-to-middle income earners more.

The results of the poll show that the majority of Australians aged under 65 give their support to the Opposition, while retirement-aged people heavily favour the Coalition by 58.5 per cent on a two-party-preferred basis.

Social Services Minister Scott Morrison has suggested that retirees draw down on their super balances, but this has apparently not affected the government’s approval among superannuants.

Since the budget was announced the government has reaffirmed that it will not make changes to superannuation, despite calls from economists and social services organisations suggesting they remove costly tax breaks on super contributions.

The poll of 3140 people held over the past two weekends suggests if an election were held today the ALP would win with an overall two-party-preferred vote of 53 per cent, besting the government’s 47 per cent.

Abbott’s stalking horses in his own party might be feeling bolder after the polls droop.

The government has dropped two points since the last Morgan Poll on May 2.

The government’s unpopular scrapping of its generous paid parental leave scheme – replaced with a scheme that puts more responsibility on employers – has not affected its poor standing with women.

Women would vote for the ALP at a rate of 54.5 per cent against the Coalition’s 45.5 per cent. And the government is also on the nose with men who would hand the opposition a smaller lead of 51.5 per cent, representing a rise of four per cent since the prior poll.

Victorians overwhelmingly support the ALP at 56.5 per cent, followed by Queensland at 54.5 per cent and Tasmania at 53 per cent. In New South Wales, South Australia and Western Australia, the Coalition leads narrowly with 51 per cent in each state, according to the poll.

Clive Palmer’s United Party which has been reduced to the eponymous party leader and Senator Dio Wang has had its vote weakened by half-a-per cent to one per cent. That support appears to have swung to the Greens which is up to 13 per cent, the poll states.

Pollster Gary Morgan suggested the ALP’s gains are due to its push for same-sex marriage, which was introduced as a private member’s bill in the parliament on Monday.
