In the midst of the Civil Rights Movement, Congress signed the 1965 Voting Rights Act in hopes of prohibiting racial discrimination in voting. This act allowed for the formation of "majority-minority" districts, which was suppose to avoid the process of redistricting plans that would diminish the ability of a race to elect its representative of choice. Additionally, the Voting Rights Act intended to use gerrymandering to combat racial inequality specifically in the South. However, the process of gerrymandering today is actually used to manipulate district boundaries to create partisan advantaged districts.
In this court case, it was a struggle between the Democratic and Republican power. For the majority of the elections for seats in the Assembly the Republicans had won. When the Democrats realized something was wrong, the Democrats of Pennsylvania decided to sue the Republican-controlled Assembly for gerrymandering the state's congressional maps. What this means is that the Republicans were making the districts in each state, gerrymandering, to make sure they would win the majority seats in the Assembly. This exact same case is happening, but in Wisconsin. It has been said that the outcome of this Supreme Court case will likely set the American politics for years even decades. Even though this case just happened, people are not expecting a decision until June of 2018 due to the fact that the judges need time to deliberate on this topic.
