Gerrymandering in single image
Steal an Election by Drawing a Map
This is how gerrymandering works.
Blue wins 60% on every case in votes counts.
But by redrawing the map, Yellow party can steal the election, or Blue party can take total control.
The person who draws the map decide the outcome, not the voters.
