Obama wins Virginia; GOP race too close to call

Barack Obama has won Virginia’s Democratic primary, defeating Hillary Rodham Clinton.

Obama is also hoping to capture first place in Tuesday’s Democratic primaries in Maryland and the District of Columbia.

Republicans are voting, too, and it looks like Mike Huckabee is making an unexpectedly strong challenge to John McCain in Virginia.

The Associated Press made its Democratic call based on surveys of voters as they left the polls.
