RICHMOND - Republican George Allen has conceded the Virginia US Senate race to Democrat Tim Kaine.
Allen made the announcement just before 11:00 p.m.
"This campaign was for the people of Virginia," he said.
The two former governors were vying for the seat being vacated by Democrat Jim Webb.
Allen said he called Kaine and congratulated him on the win and pledged his support.
Kaine accepted the win around 11:10 p.m.
The victory denies Republicans an open seat they targeted for more than a year in hopes of ending Democratic Senate rule.
For Allen, it was a bitter second loss for the same seat, one that leaves his once-bright political future in doubt.
Allen held the seat from 2001 to 2007, losing re-election to Democrat Jim Webb in a 2006 campaign marred by Allen's use of the slur "macaca" aimed at a Virginia-born Webb campaign aide of Indian descent.
Kaine, a former Democratic National Committee chairman, depicted Allen as a bare-knuckled GOP partisan hostile toward bipartisan compromise.
As of 11 p.m., Democrats had locked up 50 seats, including independent Bernie Sanders, enough to maintain control.
