partisan gerrymandering

Partisan gerrymandering is the practice of drawing electoral district boundaries to entrench the political advantage of one party, typically by concentrating opposing voters into a few districts or spreading them thinly across many. It is distinct from racial gerrymandering, though the two can overlap. There has been a wave of unprecedented mid-decade redistricting after the 2026 Louisiana v. Callais decision, which Donald Trump encouraged as a means of gaining congressional seats.
