Obama gets 2 and 3 times the votes of Clinton!

With a clean sweep in the so-called "Potomac Primaries" on Tuesday night, Senator Barack Obama brought his winning streak to eight in a row against Democratic presidential rival Senator Hillary Clinton. But more important, the elections gave Obama the lead in delegates in his neck-and-neck race with Clinton.

What is notable about Obama's wide-margin wins in the District of Columbia, Maryland and Virginia is that exit polls show he drew support not only from the groups that have already been backing him — black voters, young people, independents and those with high incomes — but also among groups that have been Clinton's core constituency, including older voters, women and lower-income people, according to The New York Times.

In Washington, Obama took 75% of the vote to Clinton's 24%.
In Maryland, Obama had 60% to Clinton's 27%.
In Virginia, Obama had 64% to Clinton's 35%.

ADDENDUM
Are they the "Potomac" primaries or the "Chesapeake" primaries? Seems like alliteration won out, though "Chesapeake" is certainly more geographically accurate:
