No.
I had no interest at all in "how is Bush handling Iraq" as a question. That's filtering every aspect of this through the Bush Derangment Syndrome again, where every question is dealt with by how Bush feels about it, or how he would be affected by it.
It's better if you go down to the Pew poll, which goes back further in time, and asks direct questions about Iraq. The decay in opinion is obvious, but while I'd have to graph it, I see no real point where it drops off drastically.
