Our weekly look at the loudest screech from the mainstream media features NBC political director Chuck Todd dissing Rasmussen Reports, the big polling firm that was among the closest to call the the 2008 presidential election correctly.

On Wednesday's Squawk Box on CNBC, Todd said: "We spend a lot more money polling than Scott Rasmussen does. We spend a lot more money on quality control....I hate the idea that their [NBC News/Marist] polling, which is rigorously done, has to get compared to what is, in some cases, you know, slop."

Media Research Center Vice President of Research Brent Baker explains our pick: "In the midst of questions about whether NBC and other mainstream media polls have tilted the playing field in favor of Obama by over-sampling Democrats, it takes a lot of gall to impugn a pollster who dares to defy the media's uniformity, especially a pollster who was right on target in 2008. Let's see which poll looks like 'slop' come election day."

Rating: four out of five screams.
