Pollster Strategies

Some time ago I noted the marked Republican house effects of pollsters which had the words "marketing" or "strategies" in their name.  There is some legitimate evidence on this pattern from Missouri -- in the huffington Post pollster aggregate front page every single poll by pollsters whose name includes "strategies" has Akin ahead while every single other poll has McCaskill ahead (yes Rasmussen too). Wow. I'm not claiming that the "strategies" pollsters are deliberately slanting as part of their strategies.  I'm just insinuating real hard.
