Former Gov. Tim Kaine speaks at A DNC event September. Kaine is running for U.S. Senate in Virginia.
The university, which released the poll Thursday, surveyed 1,434 registered voters. The results show former Republican Gov. George Allen at 42 percent and former Democratic Gov. Tim Kaine at 43 percent.
"That's a statistical tie. Well within the margin of error," says Peter Brown, assistant director of the institute.
The margin of error for the survey was plus or minus 2.6 percent. Brown adds that 15 percent are undecided.
"That's a lot of undecided, given that both of the candidates have been governor before," he says.
Brown says the Democrats would probably have a hard time keeping control of the Senate if they lose Virginia.
