LESS than one in five Tasmanians have backed Premier Lara Giddings as their preferred premier, according to the latest state polling.
The EMRS survey of state voting intentions, released yesterday, shows Ms Giddings' personal approval rating plummeted to 18 per cent, down 7 points from the last poll taken in May.
The poor result immediately drew comparisons to former Labor Premier Paul Lennon, who resigned from the top job just days after his support as preferred Premier dived to 17 per cent.
More of the 1000 people surveyed selected ``none of the above'' than Ms Giddings, while Opposition Leader Will Hodgman's popularity continued to grow, hitting 48 per cent.
EMRS advised the result should be treated with some caution given it was inconsistent with the steady level of support for Ms Giddings in the previous 12 months.
Before yesterday, her lowest approval rating had been 22 per cent.
Ms Giddings acknowledged the decline, but showed no signs of reconsidering her future.
``There is still a long way to go until the 2014 election and cracks are already appearing in the Liberal Party's populist facade,'' Ms Giddings said.
Six months out from the state election, it appears more Tasmanians have chosen which party will win their vote.
The number of undecideds has almost halved since May with only 17 per cent yet to make up their mind. Excluding undecideds, support for Labor remains unchanged since May at 28 per cent and the Greens are up slightly to 15 per cent.
The Liberals remain on track to win the next election as the first choice of 52 per cent, down slightly since May.
