What National Journal Doesn't Understand--or Remember--about the Senate

When National Journal's new ideological ratings of Congress came out, I wrote a quick take-down later that day. In light of the immediately evident errors and omissions in their selection and classification of roll call votes, I decided to do a more thorough review of their analysis. I chose to look at the Senate votes alone, even though there are some jarring omissions in their analysis of the House (the Iran sanctions bill, the NDAA, the Murray-Ryan budget deal). Here you can find the letter I intend to send to National Journal.
