WASHINGTON, Sept 27, 2007 (AFP) - As they stuff millions of dollars more into campaign coffers ahead of a key fundraising deadline, 2008 White House hopefuls are plotting a campaign spending binge of unprecedented proportions.

National front-runners Democrat Hillary Clinton and Republican Rudolph Giuliani and their rivals are making a frenetic dash for cash, before the latest quarterly campaign fundraising period ends Sunday.

GENEVA, Sept 26, 2007 (AFP) - Global funding for HIV/AIDS prevention and treatment must be quadrupled to 42 billion dollars (30 billion euros) over the next three years to stop the pandemic worsening, the UN said Wednesday.

The agency coordinating the fight against the disease, UNAIDS, said in a report that the 10 billion dollars expected this year was far short of meeting the target of 'universal access' to care in 2010, despite an 'unprecedented' global mobilisation of resources.

Eleven years ago, only 300 million dollars was available to tackle HIV/AIDS.
