Can't Tell the Player Without a Scorecard
The estimable Juan Cole writes up his reflections on how the Iraqi elections went (at least what we know so far) and where the challenges will be coming with this new government (mainly, states rights and secular vs. religious law as the face for government--sound familiar?) in Salon. He also breaks down the basic characteristics of the three main players--the Kurds, the Shiites, and the Sunnis--which I found to be quite helpful:

Iraq is a diverse society, but has most often sought forms of politics that deemphasize ethnicity. The price of such an approach, however, has often been authoritarian rule, as under the pan-Arab Baath Party that ruled from 1968 to 2003. In the north of Iraq, Kurds predominate. They do not speak Arabic as their mother tongue but rather an Indo-European language related to Persian (and distantly to English). Their Islam is mystical, traditional and somewhat rural, and most of them are not very interested in the minutiae of religious law. In recent years they have urbanized, as at Kirkuk and Sulaymaniyah, but have developed a relatively liberal approach to Islam and politics. Kurds had long had separatist tendencies and faced severe repression from Baghdad. Under the American no-fly zone of the 1990s, they developed a Kurdistan Regional Assembly, virtually a semiautonomous government, and now fear being reintegrated into Arab Iraq as second-class citizens.

The center-north of Iraq is dominated by Sunni Arabs. Arabs are simply populations that speak Arabic as their native language; they are not a racial category. Sunnis constitute some 90 percent of the Muslims in the world, but are a minority of 20 percent in Iraq. They honor four early "rightly guided" caliphs, or vicars, of the prophet Mohammed and lack a strict clerical hierarchy. Sunni reformists often resemble Protestants in rejecting saint-worship and mediation between God and human beings.

East Baghdad and the south are Shiite Arab territory. Shiites honor the prophet's son-in-law and cousin, Ali, as the rightful successor of Mohammed, and invest the descendants of the prophet with special honor. The Iraqi Shiites do have a clerical hierarchy, at the pinnacle of which is the Grand Ayatollah Ali al-Sistani, the chief source of religious authority.

In Iraq, the Sunni Arabs have traditionally predominated, and they have held political power until Jan. 30. During the past three centuries, a conversion movement among tribes in the south has produced a Shiite majority in Iraq. But the Shiites were most often poor, rural and relatively powerless. In the past half-century, many have moved to the cities, gained modern educations, and thrown up religious parties that aim to establish an Islamic republic with a Shiite cast.
