Gerrymandering by Packing
A gerrymandering method that concentrates the opposing party's voters into a few districts to reduce their influence elsewhere. This wastes their votes by giving them overwhelming majorities in limited areas.

How It Works
Gerrymandering by packing is a strategic manipulation of electoral district boundaries where the opposing party's voters are concentrated into a few districts. This means that these voters have overwhelming majorities in those particular districts but have significantly reduced influence in other districts. Essentially, their votes become "wasted" because they win by large margins in a few places but lose narrowly in many others.
The process begins with detailed demographic and voting data analysis. Mapmakers identify areas where the opposition's supporters are densely located and draw district lines to encompass as many of these voters as possible within limited districts. This creates "packed" districts with lopsided majorities for the opposition, while the controlling party secures more districts with slimmer but effective margins.
Why It Matters
Packing undermines the principle of fair representation in democracy. By concentrating opposition voters, it dilutes their overall political power across the region or state. Even if the opposition has significant support, packing ensures their influence is limited to a few districts, often preventing them from gaining proportional representation.
This tactic can skew election results, allowing a party to maintain or increase its power despite not having majority support across the electorate. It erodes voters' trust in the electoral system and can contribute to political polarization by creating safe districts with little competitive incentive.
Gerrymandering by Packing vs. Cracking
Packing is often confused with another gerrymandering method called "cracking." While packing concentrates opposition voters into a few districts, cracking spreads them thinly across many districts to prevent them from forming a majority anywhere. Both tactics aim to reduce the opposing party's influence but do so through opposite approaches.
Packing results in some districts with overwhelming opposition majorities, while cracking creates multiple districts where opposition voters are minorities. Understanding the difference is essential for analyzing how gerrymandering shapes political representation.
Real-World Examples
A notable example of packing occurred in North Carolina's congressional districts during the 2010s. Maps were drawn to concentrate Democratic voters into a small number of districts, allowing Republicans to win a disproportionate number of seats despite close statewide vote totals. This led to legal challenges arguing that the districts were unfairly designed to favor one party.
Similarly, in Maryland, packing has been used to create heavily Democratic districts, effectively "wasting" Democratic votes in those areas and enabling Republicans to compete more effectively in adjacent districts.
Common Misconceptions
One common misconception is that packed districts indicate strong representation for the opposition party. While those districts may have large majorities, the overall impact is negative for the opposition because it limits their influence elsewhere. Another misunderstanding is that gerrymandering always benefits only one party; in some cases, both major parties use packing and cracking tactics when they control redistricting.
Additionally, some believe that independent commissions can eliminate packing entirely. While independent commissions can reduce partisan gerrymandering, packing can still occur if demographic patterns naturally cluster voters or if commissions prioritize other redistricting criteria over competitiveness.

In North Carolina's 2010s congressional maps, Democratic voters were packed into a few districts, enabling Republicans to win a disproportionate number of seats despite close statewide vote totals.
