But public opinion polling of the kind Trump is talking about—gauging Americans' views on a policy issue or even on the president—doesn't
suffer from this weakness. We know the demographic characteristics of the population as a whole, so pollsters can be confident when they
adjust their data that they're doing it right. No predictions about some future state need to be made in order to measure what people believe
right now.
Except now we have tangible proof that these polls are being skewed to fit a narrative.
