Gillard takes on states, Greens Federal Labor has opened pre-election battlefronts with Liberal-led states, the Greens and the opposition, as a key union outlined a grass-roots campaign to save the government. Alluding to recent polling that shows the coalition widening its lead over the government, Prime Minister Julia Gillard on Thursday said voters had a clear choice between her government's plan for the future and the opposition's negativity. "The choice that matters is not the choice that you gabble down the phone to someone who rings up from a polling company," she said in Adelaide. The choice that matters is when you're standing in a polling booth with a ballot paper. With hospital funding a key election issue, Ms Gillard took aim at state premiers over cuts. After redirecting $107 million of federal money away from Victorian government coffers and into the hands of state hospital administrators, Ms Gillard said she would do the same if other states played games. "The federal government is not going to tolerate the continued playing of politics with health," she said. Opposition health spokesman Peter Dutton said it was a "sad and chaotic" decision by the Labor government, while Victorian Premier Ted Baillieu said it was a "short-term political fix." As the coalition sought a briefing on the details of Labor's proposed jobs and innovation package, the prime minister called on the Greens - who hold crucial votes in the Senate and lower house - to explain their position. The Greens have threatened to block the package, which is funded by a redirection of $1 billion in research and development tax breaks for the top 15 to 20 companies, if Labor doesn't agree to fix the mining tax and target that extra revenue to research and development. Ms Gillard responded: "We've got the spectre of (the Greens) going into the parliament to vote to protect the tax breaks of some of Australia's biggest companies including mining companies. How does this add up? But on Thursday afternoon, Greens deputy leader Adam Bandt said his party was open to supporting the bill subject to negotiations. The Greens were concerned less than half of the $1 billion would be spent on the jobs plan, with the rest going to bolster the budget bottom line. "This is worse than a case of robbing Peter to pay Paul because the cuts to R&D are not even matched by the new spending on innovation," Mr Bandt said. Opposition innovation spokeswoman Sophie Mirabella told AAP the Greens and Labor had given the tick to R&D cuts in recent budgets and the further changes would create uncertainty for industry. Opposition Leader Tony Abbott said the Greens-Labor split, announced by Christine Milne on Tuesday, would be a facade if Labor did not wind back policies foisted on it by the minor party. "If you're fair dinkum, get rid of the carbon tax," Mr Abbott told 2SM radio. Meanwhile, the Australian Workers' Union plans to train 280,000 delegates in marginal and blue-collar electorates in grassroots campaigning. "In our nation's pubs, in our workplaces, at our footy fields, AWU members will be trained, be given the tools they need to have conversations with the rest of the Australian population about the issues that actually matter," union boss Paul Howes said. Mr Howes also called out MPs briefing anonymously against Ms Gillard's leadership. Former prime minister Kevin Rudd reiterated he would not challenge Ms Gillard. "I mean that," Mr Rudd said.
