Then the oil must be out of reach of the Bush folks. Because that is the issue that gets their attention above all else.

From two previously linked articles:

He said more than one million people were being affected by ethnic cleansing. He said the fighting was characterised by a scorched-earth policy and was comparable in character, if not in scale, to the 1994 Rwandan genocide. "It is more than just a conflict. It is an organised attempt to do away with a group of people," he said.

Arab militias, backed by the government, have driven hundreds of thousands from their homes, in retaliation for a rebellion launched a year ago by two armed groups.

They accused the Arab-dominated government of ignoring the black African inhabitants of Darfur. More than 100,000 people have fled across the border into Chad, but have continued to face cross-border raids.

Then there's this:

Pro-government militias

For generations, the two Darfuri communities - African farmers and Arab nomads - have been rivals for the scant resources, the water and pasture, of western Sudan's harsh landscape. But the conflict resolution think-tank, the International Crisis Group, says a decisive factor in this war has been the help given to the pro-government militia. A recent report concluded: "These 'Janjaweed' militias have over the past year received greatly increased government support to clear civilians from areas considered disloyal." The Khartoum government flatly denies this charge.

The 'Janjaweed' militia are accused of ethnic cleansing

A senior government official in south Darfur is Ahmed Ngabo Ahmed. Asked whether the government has armed the militia, he emphatically says: "Never, never." The humanitarian consequences of this war have been catastrophic. The United Nations has described the situation in Darfur as a crisis of "enormous proportions". The survival of the hundreds of thousands of displaced is on a knife-edge.

Under intense pressure from the international community, the Sudanese government has reluctantly agreed to allow the delivery of international aid. But humanitarian workers are gloomy about the future. They talk privately of bureaucracy obstructing the delivery of help. The rains are also due to arrive shortly, and with them, the increased threat of disease and hunger.

Those doing the attacking are Arab. They are probably also Moslem, though the two are not necessarily mutually inclusive. The Black Africans are probably not the same kind of Moslem, and they probably aren't all Moslems (just like all christians don't really practice the same religion). What they aren't is Arab. They are called "tribal" Africans, and it is typical for tribal peoples (in the U.S. as well as other colonized nations) to blend allochthonous (formed somewhere else) religions with autochthonous (formed locally, on the land) religions and come up with something that is not longer exactly either one. Must piss off the fundamentalist Moslems, just like in the New World it pisses off the fundamentalist Christians.

"Politics" is probably an oversimplified answer.
