I too live in the suburbs, in SW Ohio— and in my suburb (which is one of the more affluent ones—NOT one where many people are benefiting from government-run economic/financial wealth redistribution programs), Biden signs far outnumber Trump signs— I feel like I am getting a true survey, too, because, as a result of the virus, I have been walking neighborhood for the last ~7 months— and have walked 90% of the streets in my community over the last month.
BTW, the polls are not “notoriously wrong”—they were wrong in 2016– but that is what made that election result so noteworthy— most elections, the AVERAGE of all the polls (a much better statistical indicator than any one poll) is spot on... and you (if you are a Trump supporter) should take cold comfort in that prospect for this election— most all of the pollsters have re-jiggered their survey processes and their statistical inference algorithms, to account for the things they (admittedly) missed about Trump voters in 2016– so there is much less likelihood of a hidden Trump voter reversing the indications of their polls in THIS election than there was in the LAST election.
