Redistricting is the process of setting electoral districts, rather than using uniform geographic standards, Gerrymandering is a practice of political corruption that attempts to establish a political advantage for a particular party or group by manipulating geographic boundaries to create partisan, incumbent-protected, and neutral districts. Redistricting is most effective in electoral systems with districts that elect a single representative. In these elections, the district boundaries can have a crucial impact on the number of persons elected by a party or group to a legislature. With redistricting they're consequences, the most immediate and obvious effect of redistricting is that elections become less competitive in all districts. Another effect of redistricting for incumbents is particularly advantageous, as incumbents are far more likely to be reelected under conditions of redistricting. Lastly redistricting has significant effects on the representation received by voters in redistricted districts.
I believe that redistricting districts gives an unfair advantage to the incumbent. It is operated as a tool where legislators could increase their chances of re-election, as well as reward friends and punish enemies. Once it is out in the open, voters don't like it much as they don't like other attempts to game the political system and violate a sense of fair play. Redistricting districts in a state provides less competition between parties and basically brings a monopoly to that area which is unjust for the competition. Redistricting also provides the incumbent with an advantage that makes new representatives unable to get elected so no new ideals will be able to be voiced in congress. Finally, redistricting does not show correct representation.
