Biden sweeps all 7 of Tuesday's presidential primaries

ANNAPOLIS, Md. -- Joe Biden has scored a clean sweep of the seven states conducting Democratic presidential primaries on Tuesday, not at all a surprise given that the presumptive Democratic nominee has no active opposition.

Yet the delegate haul is important to Biden’s goal of gaining enough delegates to claim the Democratic nomination before the party’s summer convention. Tuesday’s results may leave Biden just short of the 1,991 delegates he needs, but primaries next week in Georgia and West Virginia could put him over the top.

Of Tuesday’s elections, Pennsylvania’s could add the most delegates to Biden’s count. He also won contests in Maryland, Indiana, Rhode Island, New Mexico, Montana and South Dakota.

Also choosing a nominee Tuesday are voters in the District of Columbia. Those results are pending.
