Fact check: When was the last time the Democratic Party gerrymandered to draw new redistrict maps

1. Summary of the results

The analyses reveal that none of the sources provide a specific date for when the Democratic Party last gerrymandered to draw new redistrict maps. However, the sources do confirm that Democratic gerrymandering is an ongoing practice. The analyses indicate that Democrats responded to match Republican gerrymandering after the 2020 census ^[1], and that in states where Democrats control the process, they have redistricted just as ruthlessly as Republicans, citing examples in Illinois, New Mexico, and Nevada ^[2].

The sources focus heavily on recent Republican redistricting efforts in Texas, with Texas Democrats fleeing the state to protest GOP redistricting plans ^{[3] [4] [5]}. In response to these Republican actions, Democrats in New York and California are considering redrawing congressional maps ^[6] and Democratic governors are ready to fight against Texas Republicans' redistricting efforts and may draw new congressional maps to favor Democrats ^[7].

2. Missing context/alternative viewpoints

The original question lacks crucial context about the cyclical and retaliatory nature of gerrymandering between both parties. The analyses reveal that gerrymandering is not a one-sided practice - both parties engage in redistricting manipulation when they have control ^[2].

Missing from the question is the understanding that Democratic gerrymandering often occurs as a direct response to Republican gerrymandering efforts ^{[1] [6] [7]}. The sources suggest that rather than asking "when" Democrats last gerrymandered, a more accurate framing would acknowledge that both parties continuously engage in gerrymandering whenever redistricting cycles occur and they have the power to do so.

The question also fails to acknowledge that redistricting happens on a state-by-state basis, making it impossible to pinpoint a single "last time" for the entire Democratic Party, as different states control their own redistricting processes at different times.

3. Potential misinformation/bias in the original statement

The framing of the question contains an implicit bias by suggesting that Democratic gerrymandering is an isolated or infrequent occurrence that can be pinpointed to a specific "last time." This framing ignores the systematic and ongoing nature of gerrymandering by both parties as revealed in the analyses ^[2].

The question's structure implies that Democratic gerrymandering might be unusual or noteworthy enough to warrant identifying its most recent occurrence, when the evidence shows that both parties engage in gerrymandering as standard practice whenever they have the opportunity ^{[2] [7]}. This could mislead readers into believing that gerrymandering is primarily a Democratic practice requiring special scrutiny, rather than understanding it as a bipartisan political strategy employed by whichever party controls the redistricting process in each state.
