With the midterm election fast approaching, there’s a great deal of speculation about the accuracy of the polls. Democrats are generally hoping that the polling is right, as it suggests they are poised to take control not only of the House of Representatives but probably also the Senate. Correspondingly, Republicans are hoping the polls are wrong. They speculate that conservatives are more distrusting of pollsters and therefore less apt to respond to their inquiries, and that the polls aren’t adequately adjusting for this.
There is no way to know for sure whose hopes are more realistic. At the same time, we aren’t flying completely blind. We now have a track record of Senate polling across five prior federal elections in the Donald Trump era. If we assume that polls will perform as they have typically performed on a state-by-state basis throughout this era, what would that mean for this election?
