US President Barack Obama (R) speaks as former President Bill Clinton looks on during a campaign event in New York on June 4, 2012.
Clinton looms large in this year's presidential race - President Bill Clinton was chosen to announce President Obama's nomination at the Democratic National Convention next month. Many people believe the choice was made because he's still a symbol of prosperity and fiscal responsibility.
Meanwhile, Mitt Romney has attempted to draw negative comparisons between Obama and Clinton, claiming in a recent ad that Obama is undoing some of Clinton's reforms. We look at President Clinton's role in this year's campaign.
