Scientific polling, based on the laws of probability and the compounding of likelihoods, is a mathematical activity. It’s all about the numbers. Without the numbers no poll has meaning. That’s why I highlight key facts like Margins of Error.
Your typical internal poll release is very low on numbers and instead is a one page memo. Those releases can be based on sound polling practices, but they are firstly designed to push an agenda. When I see this new Illinois poll, I am reminded of an internal poll release.
