Sixth District polling

Some outfit called Constituent Dynamics polled a bunch of House races, including the 6th district here in Minnesota. I have no idea who they are, and I have read strange things about their methodology (do they use names or not? The report just says "nominee" instead of using any names.) But the results show the Republican nominee (that would be Michelle Bachman) up over the DFL nominee (that would be Patty Wetterling) 53-42. Certainly not as close as many people would believe if these numbers reflect reality.
