I don't believe RCP tries to judge pollsters accuracy at all, they just throw it into an average and call it done. So they get flooded by bad rightwing polls and end up saying Republicans are winning while places like 538 say the opposite. The NYT polling averages someone else posted have Harris up in NV, WI, and PA, which flips the race.
Yep. Need PA and either AZ or WI to make it work. As
Much as RCP doesn’t always show the numbers I personally want, it does seem to have accurate polling.
