Hi Peter, thanks for the comment. Yes my point in writing this article was more to frame a response to the tactic Trump employed to discredit polling: he called them all wrong & said they were a form of suppression.

Of course, as you note, there will always be a margin of error in polling, but I think it's very important to explore the research around the efficacy of the polling methodology used as I have in this article.

Thanks for reading.

Nicola
