Are we really at the point where people want polls they don't like kept out of the database? The only thing that should be excluded is internals. Not every single poll is accurate, but they still get entered regardless.
Because the pollster recalled the poll. This would be like the Gravis poll that was recalled and replaced. The pulled Gravis poll would have to be removed from the database and replaced with the new one as Gravis doesn't stand behind the original poll. There is no October Rassmussen Kansas poll to put into the database at this moment. Rasmussen recalled it.
