It's not like I had a good answer to this, so I'm not sure it's actually bad news.

Sep 14 - Portions of Iraq’s Sunni minority who live in the more rebellious population centers may be disenfranchised, US-installed interim Prime Minister told The Australian in an exclusive interview. Allawi insisted that elections would go on as planned, but said they might not be possible in some unstable cities.

"If for any reason 300,000 people cannot vote because terrorists decide so," Allawi said, "then frankly 300,000 people... is not going to alter 25 million people voting. What we are after really is implementing the political process."

Of course there are many Shia who won't be upset - who figured the Sunni would be an outnumbered and powerless minority in any event. If Allawi is serious about making democracy work, this increases the need to make them feel included. I honestly don't know how. I gather he's trying to reach out to those, Sunni and Shia, who support the insurgency. I can't find many details in English language sources - but if he knows what he's doing it could be great news.
