Fact check: What red states have been gerrymandered in the past 10 years

Checked on August 6, 2025

1. Summary of the results

Based on the analyses provided, multiple red states have engaged in gerrymandering over the past 10 years. The most comprehensive list identifies the following red states: Texas, Florida, North Carolina, Ohio, Indiana, South Carolina, Utah, Tennessee, Georgia, and Wisconsin [1].

Texas emerges as the most frequently cited example, with sources noting it was gerrymandered in 2003 and is currently undergoing redistricting again, potentially allowing the GOP to gain up to five additional seats [2]. Additional red states mentioned include Iowa, Arkansas, and Oklahoma as states that have been gerrymandered to favor Republicans [3].

Several sources specifically highlight mid-decade redistricting efforts, with Texas, Colorado, Georgia, and North Carolina identified as states where Republicans have attempted to redraw congressional maps outside the normal decennial cycle [4]. Ohio is also mentioned as a state where Republicans may attempt to add seats through gerrymandering [5].

2. Missing context/alternative viewpoints

The original question focuses exclusively on red states, but the analyses reveal that gerrymandering is not unique to one party [6]. This framing omits the broader context that both Republican and Democratic states engage in gerrymandering practices.

The analyses also provide important procedural context missing from the original question: state legislatures and courts play crucial roles in the gerrymandering process [6]. Additionally, some states are exploring mid-decade redistricting rather than waiting for the traditional post-census redistricting cycle [7].

Political parties and incumbent politicians benefit significantly from gerrymandering, as it allows them to secure electoral advantages and maintain power. The Republican Party specifically benefits from the gerrymandering efforts in the identified red states, as these efforts are designed to maximize GOP representation in Congress and state legislatures.

3. Potential misinformation/bias in the original statement

The original question contains an inherent bias by focusing solely on "red states" without acknowledging that gerrymandering occurs across the political spectrum. This framing could mislead readers into believing that only Republican-controlled states engage in this practice.

The question also lacks temporal specificity beyond "the past 10 years," which could lead to confusion about whether certain redistricting efforts are completed gerrymandering or ongoing attempts. For example, the sources indicate that Texas is currently undergoing redistricting [2] [8], suggesting this is an active process rather than a completed historical event.

The phrasing "have been gerrymandered" implies a passive process, when in reality gerrymandering is an active political strategy employed by state legislatures and political parties to gain electoral advantages. This linguistic choice obscures the intentional nature of these redistricting efforts.
