There are a lot of things that can be learned from this data, which comes from Nate Silver at 538. This is some of the most important statistical information I've seen in a long time.
If you have a cell phone, you seem to be more likely to give an answer to pollsters that favors one position over another. You seem to be at odds with those who have land lines. What gives?
More importantly, what does this say about the demographic makeup of American society? What could be learned from properly analyzing and interpreting data that includes cell phones in polling?
From the looks of it, a great deal can be learned, if this data holds up in the final results in November. It's too bad that we have to wait that long to see if this data is really going to be significant. It does indicate to me that older people who have clung to their land lines are over-represented in current polls that eschew cell phone users.
