Gerrymandering is the practice of redrawing electoral district boundaries to benefit a specific political party or group. By strategically manipulating district lines, a party can maximize its electoral advantage over opponents. This practice impacts electoral outcomes by influencing the composition of constituencies, often diluting the voting power of particular demographic groups. Gerrymandering can lead to uncompetitive elections, where a party may dominate in certain areas regardless of overall voter preference, thereby undermining the principles of fair representation in the democratic process.
