What is the term for redrawing electoral district boundaries to favor a particular political party?

The deliberate manipulation of electoral district boundaries to give one political party an unfair advantage over another is known as gerrymandering. This practice involves redrawing voting maps in a way that can skew election results, effectively allowing politicians to choose their voters rather than the other way around. The goal is to maximize the number of seats a favored party wins, even if it doesn't represent a true majority of the statewide vote.

The term itself has a fascinating origin, dating back to 1812 in Massachusetts. Governor Elbridge Gerry approved a redistricting plan for state senate districts that was so contorted in shape, one particular district in the Boston area was said to resemble a mythological salamander. The Boston Gazette newspaper then famously combined Governor Gerry's name with "salamander" to coin "gerrymander," immortalizing the controversial practice with a memorable portmanteau.

Parties employ various tactics, such as "cracking" and "packing." Cracking involves splitting groups of opposition voters across multiple districts, diluting their voting power. Conversely, packing concentrates as many opposition voters as possible into a few districts, ensuring they win those districts overwhelmingly but reducing their influence in surrounding areas. This manipulation can lead to less competitive elections, increased partisan polarization, and a feeling among voters that their voices are not truly heard, ultimately undermining confidence in the democratic process.
