MCLEAN, VA - Former US president Bill Clinton campaigned alongside Barack Obama for the first time in the 2012 race on Sunday, making an impassioned appeal to re-elect the White House incumbent and helping his fellow Democrat raise more than $2 million.

A white-haired and noticeably svelte Clinton, 65, pounded the podium with his fingers and palms and gestured vividly while addressing about 500 Obama supporters outside the Virginia home of his friend and Democratic advisor Terry McAuliffe.

"Barack Obama deserves to be re-elected," Clinton told the crowd in his signature raspy voice, warmly introducing the man who was the main rival to his wife Hillary Clinton during the 2008 presidential primaries.

"I think he's done a good job," Clinton said. "We are moving this country forward, we are going the right direction under President Obama's leadership."

When he took the outdoor podium, Obama, 50, noted Clinton's "remarkable" economic record in his two White House terms and referred frequently to the political powerhouse standing behind him, who stands to be a huge fundraising force in the final months of this year's campaign.
