Who uses the power to Gerrymander and why?

Gerrymandering is typically used by political parties in power to manipulate electoral district boundaries in their favor. By strategically redrawing these lines, they can maximize their electoral advantage, often diluting opposing voters' influence or concentrating their own supporters in specific areas. This practice is employed to secure more seats in legislative bodies and maintain political control during elections. Ultimately, it undermines fair representation and can lead to significant disparities in electoral outcomes.
