All eyes are on former US president Bill Clinton as he prepares to give a speech to the Democrat party convention in Charlotte, North Carolina.
Still highly respected by two thirds of American voters, Clinton is perhaps seen as the party’s most valuable weapon as President Barack Obama struggles to fight for a second term in the White House.
Polls show Obama is neck and neck with Republican hopeful Mitt Romney.
Obama has presided over the biggest economic slump since the Great Depression. Some analysts think Clinton’s support could be key in turning around his fortunes.
Obama will formally accept the Democrats’ nomination to run for a second term as President on Thursday night.
His wife Michelle got a standing ovation from the convention crowd for her speech on Tuesday.
But opponents warn that both Clinton and the first lady are distractions from a subject the president is keen avoid…the struggling US economy.
