Old Winston Group primary polls - Biden leads Aug, Sep, Oct

[TiltsAreUnderrated]

Only dug up by 538 now for whatever reason. Each has a sample of about 670 registered voters who are not Republican (67% to the nearest integer of a full sample of 1000 registered voters). No MoE is given for this subsample, and presumably a lot of independents who ultimately did not vote in the primaries skew it a fair bit. Still, here are the results for posterity.
