Check out these pollster ratings against the numbers in Pennsylvania
In order of the pollsters ratings:
Trafalgar Group - Trump +1
Insider Advantage - Trump +2
Emerson College - Trump +1
Marist - Even
WaPo (Ipsos) - Even
CBS (YouGov) - Even
NYT (Sienna) - Harris +4
CNN / SSRS - Even
Quinnipiac - Harris +5
Two other pollsters showing Harris leading were not rated. But all of the higher rated pollsters show Trump winning and all of the lower rated pollsters show Harris winning. Just to confirm, all of these pollsters had a lean to the left in 2020 and some (like Quinnipiac) missed 100% of the time to the left.
On a national scale, two of the pollsters showing Trump leading are in the top five of the pollsters - AtlasIntel (#1) and Rasmussen (#5) while the other is NYT Sienna. Funny how the higher the pollster rating, the better Trump is doing in those polls.
Almost like some pollsters have an agenda which doesn't include accuracy.
Some do give cover to future fraud.
