Wait, this thread hasn't reached 10 pages yet? lol
Anyway, I haven't really followed any of these races, but I really doubt that Herring is tied with Adams. Still Lean D IMO, Northam should win by 2-4, though I could definitely see Democrats outperforming the polling average this time, which seems to be an underrated possibility (especially if we include polls like this and that Hampton poll).
I'll just wait for the election at this point. No use getting hung up on polls. They can either tell you whether a seat is safe or competitive to some degree. I learned my lesson in 2016.
