SYDNEY, Australia (AP) _ Election results from Australia show opposition leader Kevin Rudd leading in his effort to become Australia's first new prime minister in 12 years.
More than 13 million Australians cast ballots today.
Neither side is conceding anything as the vote counting continues.
But returns suggest enough support is swinging away from Prime Minister John Howard's government to put Labor in power.
The pro-U.S. Howard has held power for more than 11 years and is Australia's second longest serving prime minister.
Besides being dumped as prime minister, he's also at risk of being kicked out of Parliament.
If that happens, Howard would be just the second prime minister in Australia's 106-year history of federal government to lose his place in Parliament.
The election of a Rudd government would usher in big changes in the country's approach to global warming and its troop deployment in Iraq.
Howard has refused to sign an international accord on greenhouse gas emissions.
He's also said Australian troops will stay in Iraq as long as they're needed.
