Senator Clinton is the projected winner in West Virginia tonight, according to CNN.
While Clinton is still trailing Obama in delegates by a wide margin, this win was certainly necessary to boost her campaign.
The New York Times brings up an important point:
"Given Mr. Obama’s leads in the popular vote and delegates, the West Virginia results are likely to have little practical effect on Mrs. Clinton’s chances at winning the nomination. Yet a Clinton victory in another general election battleground state — like her victories in Ohio and Pennsylvania this spring — could raise anew questions about Mr. Obama’s ability to take swing states in a contest against Senator John McCain in the fall."
