Dewey Wins in a Landslide!
That's what polling gets you.
FWIW, it happened just as people were getting phones in their homes. Richer people got 'em first - and you can guess what went wrong.
We've been going through a similarly seismic change in personal communications. I would guess the only people being surveyed for polls are people who actually *want* to be polled. Pollsters are pretending that those people are somehow representative of the rest of us who are actually going to vote - or have already.
