Gerrymandering Explained

In a representative electoral system, gerrymandering is the political manipulation of electoral district boundaries to create an unfair advantage for a party, group, or socioeconomic class within a constituency. It usually occurs the year after the U.S. Census (decennial), typically with the state’s legislature determining Congressional boundaries. Gerrymandering has the potential to impact any legislative entity requiring district delineation, encompassing the US House of Representatives as well as all state legislatures. Historically, both major political parties have engaged in this practice when given the chance. Given the consequential nature of political power, disputes over redistricting frequently escalate into highly contentious battles. 


The term gerrymandering is also sometimes used to describe somewhat different redistricting scenarios. Racial gerrymandering can mean diluting the voting power of certain racial or demographic groups, which is usually entangled with seeking partisan advantage, and a bipartisan gerrymander is a redistricting meant to protect the incumbents of both parties.


While this might seem to be a complex concept, it is quite simple to understand, once visually represented. 


Take a look at this diagram from the Washington Post:



In this example, let’s assume that there is an extremely small state of 50 people. Thirty of them belong to the Blue Party (Democrats), and 20 belong to the Red Party (Republicans). In an ideal world, let’s just presume that they live in a nice gridlike structure, with the Blues and Reds separated.


Now, it's the year after the US Census and we need to divvy up the state into 5 congressional districts. Ideally, congressional representation should be proportional to the political divide in the area. If 60 percent of our residents are Blue and 40 percent are Red, those five seats should be divided the same way (3 Blue and 2 Red representatives). This ideal scenario is represented by Grid 1, a perfect representation, as intended by the designers of our current representative system.


Now, consider a scenario where the Blue Party controls the state legislature, granting them the authority to dictate the configuration of electoral boundaries. Instead of adopting a vertical approach to districting, they opt for a horizontal arrangement, resulting in each district containing six Blue Party members and four from the Red Party. This layout, as depicted in grid 2 above, is described as "compact but unjust." Given the significant Blue Party presence in this state, each district elects a representative from the Blue Party to the House of Representatives. Obviously, the Blue Party secures five seats, leaving the Red Party without any representation. 


Finally, let's look at a scenario where the Red Party has majority control of the state legislature. They know that they can’t feasibly win an election, so the Reds gerrymander, shown in grid 3 as "neither compact nor fair." Through this tactic, they divide the Blue population in a manner that ensures a majority in only two districts. Therefore, despite only having 40 percent of the total population, the Reds managed to secure 60 percent of the available seats, leading to a partisan divide that looks like this:

Simply speaking, most attempts to gerrymander can best be understood by two basic techniques: cracking and packing.


Cracking splits particularly strong groups of people with similar characteristics, such as voters of the same party, across multiple districts. With this voting strength divided, these groups struggle to elect their partisan candidate in any of the districts, giving the other party an advantage.

Packing can be easily understood as the direct opposite of cracking. In packing, map drawers cram certain voters into as few districts as possible. In these few districts, the “packed” groups will most probably elect the candidate of their choosing, but their groups’ overall voting strength is weakened everywhere else.

Cracking and packing can also result in regularly shaped districts that look appealing to the eye but skew heavily in favor of one party, like this congressional map of Texas.

In essence, gerrymandering is a practice deeply intertwined with the dynamics of power and representation in democratic systems. Its implications extend far beyond mere political maneuvering, affecting the very foundations of fair and equitable governance. Whether it's the deliberate dilution of certain demographics' voting power or the strategic manipulation of electoral boundaries to secure partisan advantage, gerrymandering undermines the principles of democracy by distorting the will of the electorate. Despite its complexity, the fundamental techniques of cracking and packing elucidate the mechanisms through which electoral outcomes can be engineered to favor one group over another. As illustrated by the examples provided, the ramifications of gerrymandering are far-reaching and underscore the ongoing struggle to uphold the principles of fairness and equality in the electoral process. Ultimately, addressing the issue of gerrymandering requires not only a comprehensive understanding of its methodologies but also a concerted effort to enact reforms that promote transparency, accountability, and genuine representation for all citizens.
