While I really don't put a lot of credence into polling when it comes to determining caucus results, especially more than a month out, I must be missing the part where Edwards is doing better in this poll?

It appears to me he peaked in July and is now back at his usual 20-22%?

If anything this polls shows the nature of polling in Iowa, the results are all over the place for the "top 3".
