The HEMP party’s lead candidate for a West Australian senate seat says talk of his “grassroots” group winning its way into parliament is a load of guff.

The HEMP party’s lead candidate for a West Australian senate seat doesn’t expect to win, saying talk of the grassroots group getting into the federal parliament is a load of guff.

Liberal Party candidate Linda Reynolds and Defence Minister David Johnston have warned the Help End Marijuana Prohibition (HEMP) party’s James Moylan could win a seat in a re-run of the senate election in Western Australia due to preference flows from the Palmer United Party (PUP).

The PUP has preferenced the HEMP party seventh out of 33, ahead of the Liberals.

“It’s scandalous that Palmer preferences may well give Western Australians a senator who doesn’t even live here and won’t fight for WA,” they said.

But Mr Moylan, from Queensland, said the joke was on the Liberals as HEMP was “playing the political game” to raise consciousness about marijuana prohibition, arguing for its regulated use for personal, medical and industrial purposes.

“I’m unlikely to get elected unless there’s an incredible swing to Labor and that’s not going to happen,” Mr Moylan told AAP.

“We’re a really grassroots organisation and our mission is to talk with every other political party and make them negotiate on our issue and then allocate our preferences.”

“I think they’re talking a load of guff most of the journos who are really pumping it up – I just don’t think they understand the preference flows properly.”

Mr Moylan also laughed off a gaffe earlier this week when he briefly forgot the name of West Australian Premier Colin Barnett as he stood beside a giant inflatable joint at the HEMP party’s campaign launch outside the state parliament.

“Standing in front of the cameras, I just had that total brain freeze – maybe I should have had breakfast,” he laughed.

“I kick myself over things like that, but it’s cool.”
