In an email to readers encouraging recipients to read the National Journal article on the magazine's Senate ratings, the National Journal Group wrote: "We expect this story will have immediate traction in the media and blogosphere and at watercoolers around the country. In 2004, President Bush invoked Senator John Kerry's liberal Vote Ratings score repeatedly on the campaign trail and at their head-to-head debates." However, the email did not note that the National Journal has acknowledged the methodology it used to produce its Kerry "most liberal" rating was flawed.
Media Matters for America has identified numerous media outlets or figures who reported that the National Journal has rated Sen. Barack Obama "the most liberal senator in 2007," but did not report that the same National Journal feature stated that Sen. John McCain "did not vote frequently enough in 2007 to draw a composite score. He missed more than half of the votes in both the economic and foreign-policy categories."
