Joe Biden promises to unite the US on final election push in Philadelphia

Joe Biden addressed supporters in Philadelphia on Tuesday, saying that if he gets elected President there won't be "red states or blue states, just the United States of America". With almost 102 million Americans voting early and millions more waiting in line on Election Day, the rancorous campaign across a polarised nation clearly stuck a nerve with the electorate. The Democratic nominee kept his eyes on the critical state of Pennsylvania, taking his final pitch to voters in his hometown of Scranton and the Democratic stronghold of Philadelphia.
