MYSTERY: Why don't Hillary's supporters vote in internet polls???

112. And that last paragraph doesn't apply to phone polls because....?

All an online poll does is show how the people who decided to vote in an online poll voted. It is literally impossible to make any conclusions beyond that.

And a telephone poll shows how the people who decided to vote in a telephone poll voted.

Additionally, we recently "crossed the line" where a majority of households no longer have a landline. Which means you can't robo-dial a majority of households. Legally, the pollster has to type in the number by hand, greatly slowing down polling.

So we're now getting things like a recent PPP poll that was 80% landline, 20% online. That landine part is no longer representative of the overall population. And the landline part still has a self-selection bias - caller ID means lots of people no longer bother picking up for numbers they do not recognize.

Long story short, we're going to have to change how we do polling, because the results are going to get less and less accurate as time goes on.
