SurveyUSA overweights the RAT sample severly. Its polling is an outlier. Last week, the had Zero +15 over Mac in Iowa.
SurveyUSA doesn’t overweight anything.
They call who they call and use whoever they get. They are one of the few outfits that doesn’t use weighting
The sample was 49% Dem, 40% Rep, 10% Ind because thats who answered the phone.
