Indeed, as The New York Times’ Nate Cohn has pointed out, Republicans were not any less likely to answer their polls than Democrats were once we control for demographics. (If those controls had not been in place, the polls would actually have too many Republicans relative to their registration percentages.)

A slightly hopeful sign for Trump backers looking for hidden Trump support is an examination of polls that don’t use live interviews. Most of these polls are done online or with an automated voice.

An accepted polling practice to see if voters are afraid to give a certain answer they deem to be socially undesirable is to compare the results when a live interviewer is present and when one isn’t.

Biden’s national lead is still 8 points in polls that don’t use live interviews at this point. That is a little lower than in polls that do use live interviewers and call cell phones, though that gap has only recently appeared and may just be a statistical artifact.
