Oct. 4: RCP average 43.5%; Rasmussen 51%

Why the discrepancy with Rasmussen?
1) Democrat Party ID overweighted (6-7% over Repub)
2) Trump’s estimated true approval (90% Repub, 43% Independent) reduced to 78-84% and 35-38%.
Calculate adjusted Trump approval based on
1) PollID = pollster Party ID*pollster approval
2) Adj1 = pollster Party ID*adjusted approval
3) GallupID = Gallup Party ID*pollster approval
4) Adj2 = Gallup PartyID*adjusted approval
