The Public Policy Polling survey of 547 Virginia voters conducted May 5-8 shows Kaine with 46 percent of the vote to Allen's 44 percent. But the difference is well within the poll's 4.2 percentage point margin of error.
A Washington Post poll released over the weekend showed the two former governors tied with 46 percent each.
Voters are closely divided in their feelings about both in the Public Policy survey, with 42 percent having a favorable opinion of Kaine to 41 percent with an unfavorable one. For Allen, 36 percent had a favorable opinion compared to 42 percent unfavorable.
