US Vice President Joe Biden, who ran for president in 1988 and 2008, has not ruled out a 2016 run for the White House, he said in an interview broadcast Friday. "There may be reasons I don't run, but there's no obvious reason for me why I think I should not run," Biden told CNN. dpa cited him as saying he expected to make a decision next summer. To date, former secretary of state Hillary Rodham Clinton has been the clear favorite from the Democratic Party to succeed President Barack Obama, a fellow Democrat, although she has yet to announce her intentions. A recent Washington Post/ABC poll of Democratic voters showed Clinton leading Biden by a margin of 73 per cent to 12 per cent. -- SPA 19:10 LOCAL TIME 16:10 GMT تغريد
