Statistics and politics don't mix well, not matter what field you're in. Trust me.
Statistics aren't difficult, but they frequently have too much nuance for the average observer who hasn't studied them to really glean anything worthwhile from them.
Which is why polling date is useful by some measures to people who understand it, but is worthless and even potentially detrimental to people who don't know what they're looking at.
Which is like 95% of people reading articles on CNN or Fox or w/e.
