Gerrymandering in the United States

Gerrymandering is the practice of setting boundaries of electoral districts to favor specific political interests within legislative bodies, often resulting in districts with convoluted, winding boundaries rather than compact areas. The term "gerrymandering" was coined in 1812 after a review of the redistricting maps of Massachusetts set by Governor Elbridge Gerry noted that one of the districts looked like a mythical salamander.
