SurveyUSA's latest poll slams another nail in Virginia Democrats' coffin, as it shows Republicans leading each of the top three races on the ticket by at least 16 points -- including gubernatorial nominee Bob McDonnell up 18 points. The potential GOP sweep tomorrow would certainly be a blow to Dems, who have enjoyed a run of statewide success in recent years.

McDonnell now leads by 14.0 points in the RCP Average for Virginia. Both candidates will be in Richmond tomorrow night, on opposite sides of the city.
