'Give it a go, Joe': US union crowd cheers on Biden

  PITTSBURGH — Hearing chants of "run Joe, run," Vice President Joe Biden marched in a parade marking the U.S. holiday of Labor Day on Monday as speculation swirled about a potential late entry into the Democratic presidential campaign. Biden is seriously considering one more run for the White House. His entry could jumble a Democratic contest that has seen front-runner Hillary Rodham Clinton's lead diminish in early voting states. The vice president donned a black-and-gold United Steelworkers union hat and told hundreds of union members that the gap between the wealthy and poor was hurting Americans. "The tax code's not fair. It's simply not fair," Biden said in a city long associated with organized labor. "The wealthy aren't paying their fair share. There used to be one America." Biden later marched throughout the city's downtown, hearing encouraging words along the parade route. "Give it a go, Joe!" shouted one woman. Underscoring the volatile nature of the race, an NBC News poll released Sunday showed longshot candidate Sen. Bernie Sanders gaining an advantage over Clinton in the key state of New Hampshire, where Bill and Hillary Clinton have maintained deep ties during their political careers. Biden has run for president twice before, including in 2008, when he was outpaced by Clinton and President Barack Obama. Biden, who suffered the death of a son earlier this year, said last week he wasn't certain if he and his family had the "emotional energy" for another campaign. An influential labor leader, AFL-CIO President Richard Trumka, said the vice president got a strong response from workers in the industrial city of Pittsburgh after walking the parade route with Biden. — AP
