Gerrymandering is the practice of manipulating electoral district boundaries to benefit a particular political party or group. This often results in districts that are irregularly shaped to maximize the number of votes for a party, leading to unfair advantages in elections. Gerrymandering can dilute the voting power of certain demographics, effectively changing the political landscape and undermining the principle of fair representation. It can diminish electoral competition, leading to a lack of accountability and responsiveness from elected officials.
