Aide hints Joe Biden will seek Democratic nomination for presidency
US vice-president Joe Biden sent a clear signal through his political team that not only might he enter the presidential race soon, he has a strategy prepared that he thinks could win.
After the first Democratic debate softened concerns about front-runner Hillary Clinton there was much speculation that there was no obvious rationale for Mr Biden to run.
But in a letter to former Biden staffers, one of Mr Biden's closest advisers traced the contours of the argument the vice-president would make, and suggested a decision could be imminent.
Former senator Ted Kaufman said, if Mr Biden runs, it will be because of his "burning conviction" to restore opportunity to the middle class.
