silver is lying if he is saying this poll is an outlier.

I do think people overthink things some times. In an 800-person poll, the margin of error for the difference between candidates is ~7 points. And 1 in 20 polls will fall outside that margin of error, i.e. be more than 7 points away from the true number.

Now, in practice, pollsters may sit on their outliers or rejigger them rather than publish as in. But *good* pollsters like Selzer or ABC/WaPo *do* go with their numbers. So you’ll get the occasional Biden +17 in WI or Trump +7 in IA.
