Polls are always questioned. We had many here who questioned the poll numbers prior to the election saying they oversampled Dems even though that is not the way they are done. In fact, the polls proved to be pretty much on target along with Nate Silver of the NYT. Denial just ain’t a river in Egypt.
This is nearer augury than is all that comfortable, but as usual some pollsters came up with answers closer to the results than others ~ that doesn't mean they didn't jigger their own results to get there!
Never ever assume there are not people out there smart enough to outthink polling techniques.
