The correct answer is: When redistricting occurs, political groups try to shape electoral districts so that their parties have an advantage.
The word “gerrymander” is dated on 1812, in a political cartoon drawn to parody Massachusetts Governor Elbridge Gerry’s who re-drew Senate districts. The cartoon depicts one of the districts, as a fork-tongued mounstrous salamander. Since then, it has been increasingly used as a tool to reposition the electorate distribution. Redistricting arranges states and electorate who live there into geographical territories, but gerrymandering manipulates these districts boundaries. As in the parody described above, gerrymandering will alter and shape electoral districts for a particular party or political group, locating it in an advantageous position.
