Sectional Differences in Partisan Bias and Electoral Responsiveness in US House Elections, 1850–1980

In this Note we challenge the claim asserted in a 1984 Wall Street Journal editorial that partisan gerrymandering by Democratic-controlled state legislatures is the principal reason for the inability of Republicans to translate their national share of votes proportionally into seats in the US House of Representatives. In contrast to previous work, we show the critical importance of sectional (South/non-South) differences for understanding the dynamics of electoral change at the congressional level. We argue that the inability of Republicans to translate votes effectively into congressional seats is largely a product of wasted Republican votes in the South, although we recognize that a handful of states (e.g., California) are significantly gerrymandered against Republicans, and we also recognize that part of the reason for the present-day Democratic advantage in the House is an incumbency advantage that benefits the party that controls most seats.
