> In my understanding the overton window is a sliding frame on an axis I guess it's a technical and semantic objection: A (one dimensional) window by necessity has two endpoints, and "pole" is a word that defines a point. Your use of pole is however more in the sense of direction rather than endpoint; an axis is a direction and as such can be defined by any two points along it and no set of points have such a privileged position that they warrant the label "pole". > I find it hard to believe that there is no ideological consistency Again, it's a statement about how parties are organised and not about how people in general believe the world works. Though I suppose this circumstance also implies there is a fairly dominant agreement on the essentials of the world-view.
