Well, yes, I don't know, I'm only going off never having heard of gerrymandering being a major problem in any other country.

Plus that in general America seems to involve politics in decisions which are more usually left to officials to do in an, at least theoretically, non-partisan way. I don't know of any other country in which judges are elected by popular vote, or Ambassadors are appointed and approved by politicians instead of being professional government officials(this one I am pretty sure is unique).
