A Jacqui Lambie Network official has brushed aside Liberal-commission polling showing the party's support is on the slide ahead of next month's Tasmanian election.

MediaReach polling, conducted for the incumbent Liberal Party and published in The Australian on Wednesday, has JLN support halving in a little under a fortnight.

Will Hodgman's government faces a close fight at the March 3 poll, with a hung parliament on the cards.

Some analysts believe the JLN could end up holding the balance of power.

But the latest poll shows backing for the JLN in Braddon, Bass and Lyons - where it is running 12 candidates - has dropped off.

Braddon, Ms Lambie's backyard in Tasmania's northwest, was at 15.5 per cent in late January but had dropped to 6.1 per cent on Monday.

At Bass it fell from 11.7 per cent to 6.1 per cent and in Lyons 12.4 per cent to 5.7 per cent over the same period.

Under the state's voting system, a candidate needs 16.7 per cent of the vote to win a seat.

JLN spokesman Glynn Williams dismissed the poll as "Liberal Party propaganda".

"We have had indications from various sources and it was far more positive than the Liberal Party slant but we're not at liberty to disclose that," he said.

Mr Williams said the landline poll was skewed as it would be mostly answered by an older demographic.

"What stands out is the Liberal Party is anxious to attack the Jacqui Lambie Network relentlessly. If we weren't a threat, they wouldn't be promoting those attacks," he said.

Not running in the state campaign, Ms Lambie has drawn recent headlines, notably over her Senate stoush with Steve Martin.

She has also said donations for the JLN would be put towards her Senate bid.

"She's made decisions that haven't helped her in the public forum," University of Tasmania political analyst Richard Herr said.

"For her to also say the money being raised for the state campaign has reached its maximum, certainly seems to be self-serving than for her party's chances at the state election."

The Liberals have commissioned five phone polls of 1500 voters, with the first on January 30.
