WASHINGTON (Reuters) - After all the rancour of the Democratic presidential race, front-runner Joe Biden has a chance in Sunday's debate to extend an olive branch to rival Bernie Sanders and his fervent liberal supporters in a bid for party unity before the general election fight.
Biden and Sanders will square off in what may be the final debate of the Democratic nominating contest. Biden leads Sanders in delegates after a string of primary victories, and next week's nominating contests could put the former vice president on a nearly unstoppable path to the nomination.
