If Republicans and Libertarians and Democrats are all "Right of Center" The who's at the center and who's left of center?
It's a fair question, so the scale is broken.
yes, in our two party system (stop kidding yourself, libertarians are no less republican) someone must be at a center point--but this means such a scale no longer references typical ideals of the right and the left; but simply recognizes two differing views.
In terms of ideology, there is simply no "left" in this country. on a left/right scale, no one--no one so truly left of center any more. Both parties have a bit of a conservative base, but the current GOP has gone so far to the batshit end of right ideology....it's like they no longer have a place in this world (except, I'm starting to think they want to turn this country into a place like Pakistan)...that it's still easy to see clear differences in the ideologies of the two parties.
The polarization is still there, but the scale has moved off of the ideology scale, and is simply used to define where people sit on their "teams."
It's disgusting, and it's primarily the fault of Newt Gingrich.
