Abstract: 
Combining referendum results with parliamentary votes of proportionally-elected politicians of the Swiss Lower House of Parliament, Giger and Klüver (American Journal of Political Science, forthcoming) find that sectional and cause interest groups affect the quality of political representation. We extend their analysis to a new dataset of majority-elected politicians of the Upper House. Our results show that sectional and cause groups do not affect defection of politicians from their constituents. This suggests that the electoral system moderates the influence of interest groups on political representation.
