What is the 80/20 Poll Rule?

And while we are most intrigued by 2012 Presidential Polls, we also realize that they are the most volatile. They are good, however, for establishing floors of certain candidates for certain criteria. Prime example: Sarah Palin. We can accurately assume that Sarah Palin’s floor is at 40% because she sits their having received the full attack of the MSM, and establishment D and R operatives. And we can assume that Newt Gingrich’s ceiling is at 41%, having maxed out here despite years of no negative press (we can assume that as history revives, Gingrich will not thrive).
