Gerrymandering

Gerrymandering is about the manipulation of electoral district boundaries for political purposes.
It's almost always considered as a corruption of the democratic process and it can be used to help or hinder a political, ethnic, racial, linguistic, or religious group.
In addition to its use achieving desired electoral results for a particular party,  the main purpose is to influence not only the districting statute but the entire corpus of legislative decisions enacted in its path.
I represented here this path of manipulation.
