Media Blogs in Memeorandum Lean Left

UPDATE: View the raw data here.

I am a proud geek, and also an avid Memeorandum user, and so I jumped at the chance to install this Greasemonkey script visualizing political bias in Memeorandum. The script will highlight various blogs linking to an item in shades of red or blue depending on their linking behavior in the last three months. The script doesn't measure political bias per se, but if you've recently linked to a lot of liberal blogs, you are colored blue.

Look at the colors assigned to MSM sources and media-sponsored campaign blogs. Every single one that I could see -- except for Yahoo News in a separate link -- is colored blue:

The New York Times and the AP are colored in the darkest shade of blue, along with Talking Points Memo:

Even MSM bloggers I really like Jonathan Martin and Marc Ambinder (not included here, but the blue coloring was spotted in the wild) are colored blue. And though Martin is not a partisan, he did briefly work for National Review and covered the Republican primaries, so he should link to conservative blogs more than most.

I am personally not on the media bias bandwagon as much as some people. We've both won and lost elections with the media against us. But I tend to trust computational rather than polemical measurements thereof. Though this measurement doesn't nail political bias perfectly (FiveThirtyEight is colored light red) Google has rubbed more than a few pennies together on the idea that you are what you link to. (And the algorithm was built by Joshua Schachter, founder of Delicious, and, I'm certain, no right-wing hack.)
