Opinion polling blog posts

Why a 'greatest hits' polling blog post?

Over the past few months, I've blogged about elections and opinion polling several times. On October 8th, 2020, I gave a talk at PyData Boston on forecasting US presidential elections, and I thought I would bring these blog posts together into one convenient place so the people at the talk could more easily find them.
