Why do political parties most often try to gerrymander voting districts?
Answers
Gerrymandering is the practice of one party packing as many voters of the other party into the fewest districts possible.The purpose of gerrymandering is to grant one party power over another by creating districts that hold dense concentrations of voters who are favorable to their policies.
Two principal tactics are used in gerrymandering for example diluting the voting power of the opposing party's supporters across many districts and concentrating the opposing party's voting power in one district to reduce their voting power in other districts.The third tactic is that of homogenization of all districts.
In addition to its use achieving desired electoral results for a particular party, it may be used to help or hinder a particular demographic, such as a political, ethnic, racial, linguistic, religious, or class group, such as is the case in USA. It can also be used to protect incumbents.
