ALEXANDRIA, Virginia (CNN) - In an energetic and positive address to his supporters, former state legislator Brian Moran conceded Tuesday night in Virginia's first contested Democratic gubernatorial primary in nearly 30 years.
"Because of this primary, Creigh Deeds is now an invincible candidate," Moran said shortly after the race was called for Deeds.
He added, "We can hold our heads high."
With the primary now behind him, Moran told the crowd that he was committed to helping Deeds beat Republican nominee Robert McDonnell.
"I told him, Creigh, you're going to have me by your side," Moran said. "We're going to work as hard as we possibly can. We will win in November."
The former state legislator, who had pledged to try to repeal Virginia's constitutional ban on contractual agreements that sanctified same-sex relationships, made a point of emphasizing that pledge in his concession speech.
"We ran on this great Commonwealth making sure that we provide equality to every single Virginia," Moran said.
He was joined on stage by his wife, two children, and brother, Rep. Jim Moran.
In defeat, Moran sought to lighten the mood.
"You're going to have to go to school tomorrow, guys," Moran told his two young children. "They were hoping for a little late celebration."
