I’ve heard several pundits recently talking about how exit polls have been quite inaccurate during this election cycle. And I’ve speculated myself about how traditional opinion polling, typically conducted by phone, might become unreliable because so many people screen calls or don’t even have landlines; you end up with a self-selected population of phone-answering people that is not representative.

So here’s a question: suppose it becomes impossible to accurately poll the electorate. Suppose there is no way to find out what people want until the ballots are counted. Would there be any actual down side to that? For anyone other than the news media and the pollsters, I mean?
