From the BBC:
Obama wins primaries clean sweepSource
Barack Obama has won the
Democratic primary polls in Virginia, Maryland and the District of Columbia,
according to US media projections and early results.
The results will be a blow to rival Hillary Clinton, who has now lost a string of contests to Mr Obama.
Senator Clinton is looking ahead to primaries in Ohio and Texas on 4 March in the hope of reversing her fortunes.
For the Republicans, front-runner John McCain has beaten Mike Huckabee in all three races, according to projections.
With results counted in three-quarters of Virginia's precincts, Mr McCain led by 48% to Mr Huckabee's 43%.
A victory means he will claim all of the winner-take-all state's 60 delegates, extending his significant lead in terms of the number of delegates who will vote for him at the party's national convention.
I plan to sleep well tonight :-)
