Labor, Libs enter final week before poll PM Kevin Rudd is likely to play the underdog card amid new polls, as he campaigns in the NT. LABOR and the coalition are entering the crucial final week of election campaigning with neither side prepared to give up. Labor vowed to "fight, fight, fight" despite poor polls on Saturday as Prime Minister Kevin Rudd prepared to officially launch his campaign in Brisbane on Sunday. "I've seen a range of polls both public and private which suggest to me this election will end up a little closer than you think," Mr Rudd told reporters in the Northern Territory. Opposition Leader Tony Abbott says he expects plenty of "low" politics from Labor in the countdown to September 7 but played down polls showing a coalition victory. He plans to run a steady campaign during a tough last week, knowing the last few yards are when "the most can go wrong." "Lots of people have said to me over the course of the last three or four weeks that we are desperately hoping for a change of government and if it doesn't happen you, Abbott, are going to be held responsible," he told reporters on Saturday. Mr Rudd, who will promote Labor's message of jobs and growth at Labor's launch on Sunday, had another bad day on the campaign trail. Journalists travelling with him were prevented from touring a GP superclinic in the marginal Country Liberal seat of Solomon by the conservative Northern Territory government. Mr Rudd called it "base politics" by the NT government. But the NT government made no apologies for putting the needs of patients and health staff ahead of politicians "hot on the campaign trail." Mr Rudd used his visit to re-commit $110 million to build a second hospital in Palmerston. During his press conference, he was loudly heckled by a man who shouted "You fool! Mr Abbott also had a heckler but it was not so loud or unfriendly. Deep in the heart of beef country in the Queensland seat of Flynn, Mr Abbott said regional Australia would be a focus of a coalition government. Earlier in Townsville, Mr Abbott pledged $20 million for flood-proofing a local road as his shadow Immigration Minister Scott Morrison announced the scrapping of free government legal advice which he said will save $120 million over four years, and deter people from getting on boats. Elsewhere on the campaign, Treasurer Chris Bowen was insisting the coalition was hiding by not releasing its full list of election promises and costs - and that amounted to deception.
