All three of Tuesday's contests occurred in fertile territory for Obama, with large populations of the high-income and black voters.

Exit polls by ABC News indicate his easy win was also boosted by white Democrats and independents.

But the so-called Potomac primary is not the end of it, as both Obama and Clinton are far from the delegates needed to win the nomination at the Democratic National Convention this summer.
