"He inherited a deeply damaged economy, put a floor under the crash, began the long hard road to recovery, and laid the foundation for a more modern, more well-balanced economy that will produce millions of good new jobs, vibrant new businesses, and lots of new wealth for the innovators."

After his speech, Clinton was joined by Obama - who made his first appearance on the convention stage - before the delegates in Charlotte, North Carolina - held their roll call to officially nominate him for a second term.
