Federal law places limits on racial gerrymandering, but partisan gerrymandering is largely beyond federal court review.
A claim about partisan gerrymandering raises a key legal question: does federal law prohibit drawing political districts to favor one party? The answer is complex. Federal law does not clearly ban partisan gerrymandering, and federal courts largely cannot stop it.
Partisan gerrymandering refers to drawing electoral district lines to benefit one political party over another. Gerrymandering has existed for centuries and remains a central issue in U.S. elections.
The most important legal development came in 2019, when the U.S. Supreme Court decided the case Rucho v. Common Cause. The Court ruled that claims of partisan gerrymandering are “political questions” that federal courts cannot decide.
This means that even if a district map heavily favors one party, federal judges generally cannot strike it down on that basis alone. Legal experts describe this as leaving partisan gerrymandering largely outside federal judicial oversight.
However, that does not mean all gerrymandering is allowed. Federal law still prohibits racial gerrymandering. Under the Constitution and laws like the Voting Rights Act, maps that discriminate based on race can be challenged in court.
The difficulty is that race and politics can overlap. Courts have increasingly allowed states to defend maps as “partisan” rather than racial, which makes challenges harder to win.
Because federal courts stepped back, regulation of partisan gerrymandering now depends on:
- State constitutions and courts
- Independent redistricting commissions in some states
- Congressional action (which has not passed nationally)
Recent Supreme Court decisions have further weakened federal protections tied to voting and redistricting, making it even harder to challenge maps at the national level.
The result is a patchwork system where some states restrict partisan gerrymandering while others allow it more freely.
Final Verdict: Mostly True ⚖️ Federal law does not clearly prohibit partisan gerrymandering, and federal courts generally cannot stop it. However, other legal limits—especially on racial discrimination—still apply.
Great article, very helpful!
