To win congressional majorities, Democratic and Republican parties must stitch together coalitions that are broad enough to accommodate their stronghold districts and swing districts, but distinct enough to differentiate themselves from each other. How each party builds these coalitions depends, in part, on the demographic characteristics and policy views of voters in districts where they garner most support and how these overlap with voters in competitive districts.
In this report, we show how Democratic and Republican districts differ from each other and where they overlap with competitive districts. Democratic districts tend to be more affluent and more diverse than Republican districts, which are mostly poorer and predominantly white. Competitive districts comprise roughly equal shares of districts that are more and less affluent than the district average, but they tend to be whiter than the average district. The winner-take-all electoral system accentuates these differences and reduces the diverse constellation of districts to a binary. This results in an inadequate representation of voters in districts that are far from the median Democratic or Republican district.
