I haven’t been following them closely (or at all, really). But my throwaway guess is that Republicans lose both.
Why would lower income Trump supporters vote for the party that failed to find Trump 11,780 votes and denied them their well-deserved $2,000 worth of gibs? I certainly wouldn’t in their place.
Polling average ends in +1.8% to Ossoff and +2.1% to Warnock.
Biden was at +1.2% and won Georgia by +0.2%, so they were very accurate there.
The likely reason the polls underestimated Trump was because Trump’s support is more heavily loaded towards proles whom polls undersampled this year due to Corona (professionals worked from home and had free time to answer polls). But these proles like Trump a lot more than generic Reps, so we can expect less of an error in these elections. Plus, in any case, pollsters will have had time to further refine their methodology since the Presidential election.
