Although I can’t find the post now (not for lack of trying, mind you), in retrospect the decision to elect the Iraqi Transitional Assembly from a single electoral district was a mistake—one that it appears the Shiites are willing to rectify by retaining the proportional representation system, but using the 19 provinces as electoral districts, thus (in theory) guaranteeing greater Sunni representation in the government even if Sunni turnout is low in the first elections for the permanent government that are supposed to happen sometime in the next year.
Of course, this adds the complicating factor of having to reapportion the legislature every decade or so, and it probably will make it somewhat harder for national cross-sectarian parties to gain seats, but in the end I think it’s a reasonable compromise.
