US Senate overwhelmingly represented wealthiest constituents in last decade - study
Members of the US Senate have been the most responsive to high-income constituents over the past decade, according to a study by Political Research Quarterly. The research is based on voting records of the 107th through 111th Congresses and the 2004 National Annenberg Election Survey, which gauges constituent political opinion. Researchers found that only during the 110th and 111th Congresses did middle-income opinion reflect voting records at all. Lower-income opinion never influenced voting behavior in that period, the study found.
