Thanks to WIIIAI for the link to this former Tory MP opinion peice on Iraq. It is very good.
Brookings, who I increasingly distrust as they get more and more connected with AEI, has published 40 pages that they call the Iraq Index. I don't know where they are getting their poll numbers, but at first glance they look good. Note: The report shows a lot of graphs with the most recent month trending down. That is, in part, because the most recent month is July, and it is only one fourth over.
