Bill Clinton campaigns for Obama at Miami college

Former President Bill Clinton delivered another rousing address supporting President Barack Obama as he told college students in Florida that Republicans were a threat to education funding and healthcare.

More than 2,000 people turned up at Miami's Florida International University to hear Clinton, who last week gave a powerful endorsement of Obama at the Democratic National Convention in North Carolina.

Clinton once again touched on the theme of "shared responsibility" between government and society.

A "militant, bitter anti-government strategy" is not the way to build a modern society, Clinton told the students. "It's not business versus government the way it's set up by our opponents. It's business and government working together."

A majority of the speech revolved around healthcare and Republican presidential candidate Mitt Romney’s proposals regarding the Medicare health insurance scheme for the elderly.

"The Medicare trust fund instead of running out of money in 2024 will now go broke in 2016 because we're spending more money on it," Clinton said. "Which means either they'll have to change Medicare as we know it even eight years earlier than they promised to, or take more money away from education, not to pay for seniors on Medicare but to pay for providers."

Florida is one of several battleground states crucial to securing victory in the November 6 election.

Earlier this week, Obama concluded a two-day bus tour of the swing state, pitching his bid for re-election to independents, Latinos and senior citizens.
