The disinformation campaign is everywhere.
Polls originating with a dot edu know that their job security depends on tenure, not on "maintaining a record of reasonable accuracy".
So take some advice that I know you’re not going to take: Don’t buy the “lying polls” claim. Polls are imperfect, but generally they’re accurate. No pollster, even one who may be personally biased for or against a particular candidate, wants his name attached to a poll that predicts Dewey beating Truman. Personally biased as they may be, pollsters gotta eat too, and they know their job security depends on maintaining a record of reasonable accuracy.
