In the United States, a significant portion of elections lack competition, with around 85 percent of House seats in 2025 being decided during primaries rather than general elections. This issue is exacerbated by geographic divides between urban and rural areas within states, resulting in elected officials who may not fully represent their constituents.
Proportional representation (PR) is proposed as a solution to enhance democratic accountability by making legislative elections more competitive. Unlike the winner-take-all system where one representative is elected per district, PR allows multiple representatives to be elected from larger districts based on the proportion of votes each party receives. This approach aims to give both majority and minority voices a chance at representation and makes elections more competitive.
Gerrymandering and geographic sorting are identified as challenges to competitive elections. Even with fair district maps, Americans tend to live among those who share similar political views, leading to uncompetitive districts. PR offers a structural solution by allowing diverse representation even in regions dominated by one party.
An example cited is Massachusetts’ 2024 U.S. House Election where Democrats won all nine seats despite Republicans securing substantial statewide votes for other offices. Under PR, Republicans could have won several seats without altering the Democratic majority but ensuring minority representation.
Analysis suggests that adopting PR could increase competitive House elections from 15 percent to 43 percent. It also shifts political behavior by broadening the voter base politicians feel accountable to beyond primary voters. James Madison emphasized that representatives should remember their dependence on people—a principle hard to achieve when primaries decide power retention.
However, PR has tradeoffs such as potentially weakening voter-representative connections if districts become too large. Expanding the size of the House could mitigate this issue by reducing constituents per representative ratio. The implementation method—whether through open or closed lists—also affects whether politicians prioritize personal relationships or party loyalty.
While PR doesn’t directly address primary system flaws, it shifts decisive contests from low-turnout primaries to general elections, enhancing participation in outcomes determining law-making authority.
