Some interesting research on supposedly random and reliable social statistics on the Daily Kos

Here: A bit over two weeks ago, a group of statistic wizards (Mark Grebner, Michael Weissman, and Jonathan Weissman) approached me with a disturbing premise -- they had been poring over the crosstabs of the weekly Research 2000 polling we had been running, and were concerned that the numbers weren't legit.

I immediately began cooperating with their investigation, which concluded late last week. Daily Kos furnished the researchers with all available and relevant information in our possession, and we made every attempt to obtain R2K's cooperation -- which, as I detail in my reaction post here -- was not forthcoming. The investigators' report is below, but its conclusion speaks volumes:

We do not know exactly how the weekly R2K results were created, but we are confident they could not accurately describe random polls.


This cannot be a design inference, right?
