I would bet you that they are not looking beyond the top-line oh wow were doing way better than Republicans in VBM numbers. Quarantine is likely affecting this in the sense that nobody is gathering their organic thoughts together and many professionals are watching Netflix all day.
Been 16 years since I did any campaign work.
Do the parties still keep Voter Vaults that track votes as they come in?
I’ve run across some in various states (usually spreadsheets and no longer capable of being opened)as I did other research around the net.
Might help to enlist some campaign workers with acess across various states/counties, if possible.
