Another poll...
And at least with this one, you can get the whole poll. Bad news for some is that it's in Powerpoint format.
Page 34 asks various regions "How likely are you to vote in Iraq's elections?"
The Sunni areas have 19.9 percent saying "very unlikely," 18.5 percent as "somewhat unlikely," 32.4 percent as "somewhat likely," and 21.1 percent as "very likely." Don't know how this compares to the division of categories for Zogby, and to be fair, this poll was taken a week or so earlier than the Zogby poll.
I guess like with the November elections here, we'll see what actually happens.
