9/20/12 Pollster Open Thread

This open thread is to discuss all of the day's polls -- what they tell us about the election, their methodological strengths and weaknesses, notable findings others have missed or whatever else you want to talk about. Each day's open thread will appear in the morning and remain open for 24 hours. We also encourage you to use the "favorite" button to identify the most interesting or insightful comments. We'll review the recommended comments every day and try to highlight the best in the next day's entry.

Wednesday featured comment
“Wow, it really is a divided electorate. Romney couldn't possibly have screwed up worse in the last week, yet it's still essentially a dead heat in most polls. Seems that there just aren't any independents to swing anymore. Most have made up their mind I guess, which at this point is fine. If the election were today, the final electoral map would look amazingly similar to 2008 with an Obama win.” - orangefan244
