Biden his time or too late for a run for the White House?

Despite being 72 and grieving the recent loss of his son, questions remain about whether Joe Biden will challenge for the Democratic nomination, writes Bette Browne.

It would certainly shake up the race for the White House if US vice-president Joe Biden entered the fray. While his supporters believe he could win the Democratic nomination, the record suggests the likelihood of a Biden presidency is remote.

Biden twice sought the presidency and twice failed — once in 1988 and the second time in 2008. Now he is 72 and has little in the way of an ongoing fundraising machine to compete with rivals like Hillary Clinton, never mind Republicans.
