Creigh Deeds will be the Democratic candidate for governor in Virginia this fall.
Deeds won the Virginia primary Tuesday, beating former Clinton campaign official Terry McAuliffe and former state representative Brian Moran.
"No one could have imagined what we've accomplished her in the Commonwealth of Virginia here tonight," Deeds said. "Because of you, you've embraced Virginia moving forward and I'm standing here tonight as the Democratic nominee."
Deeds will face Republican Bob McDonnell.
McDonnell beat Deeds in the race for state attorney general four years ago by just 323 votes out of nearly two million, the closest race in modern Virginia history.
Political analysts says the race will be considered a bellewether for President Obama and the Democrats.
