One of the more surprising findings from the 2013 ratings is that liberal icon Elizabeth Warren of Massachusetts placed herself in the middle in her first year in office, ranking as the 31st-most-liberal senator (73.2 score). Most of the senator's defections were on economic issues: She voted to repeal Obamacare's medical-device tax and "to repeal or reduce the estate tax" if done in a fiscally responsible way. Warren even irked consumer advocates in opposing a measure that would have allowed states to mandate labeling of foods that contain genetically modified ingredients.

On social issues, however, she lived up to form, tying with 26 other Democratic senators as the most liberal.

What they had to say about gerrymandering is also interesting. Note the extreme number of politicians who are all over the map conservative/liberal during any given election.
