Webb Allen

Rasmussen(8/16) 42 47
Here's the last poll for last year's race
Kilgore Kaine
SurveyUSA(11/07) 45 48
(K+3)
Mason(11/02) 44 45
(K+1)
Rasmussen(11/06) 46 49
(K+3)
Final Result: 46 52
(K+6)
Looks like SurveyUSA and Rasmussen polled better although both underestimated Kaine's by about 3 points, Mason obviously overstated Kilgore and understated Kaine.
Based on those polling pattern, I would say it is probably Webb: 43, Allend: 45 at the moment.
