Quinlan, Greenburg, Rosner is an excellent firm.
They do the polling for "Democracy Corps" as well.
This poll was done mid-May at the height of the iraq prison scandal mess, so Kerry +1 or 2 was prettty darn close.
I think we really have to give due credit to Quinlan, Greenburg, Rosner on this one.
Mother Jones certainly would have liked a Kerry +23 result, or to have had something crazy like 13% more Democrats than Republicans in the poll, but these guys look like they did the Presidential preference part of the poll absolutely straight up.
Score one point for intellectual honesty and integrity
I found it "interesting" that the traditional "gap" of 3-4% between Registered and Likely voters tot he GOP side has returned in this survey. - Don't know what it means, but it's interesting.
