What it is
Gerrymandering involves manipulating the geographic shape of electoral districts, typically for the U.S. House of Representatives or state legislatures. This manipulation aims to concentrate opposing party voters into a few districts (packing) or spread them thinly across many districts (cracking), thereby diluting their voting power and increasing the chances of the favored party winning more seats. The party in control of the redistricting process often uses sophisticated demographic data to achieve these outcomes.
Gerrymandering frequently appears in news cycles during redistricting years, which occur after each decennial U.S. Census. Courts often review gerrymandered maps, with challenges focused on whether districts are drawn based on partisan intent or racial discrimination. These legal battles can delay election preparations and influence the balance of power in legislative bodies, determining which party controls state houses or Congress for the next decade.
Why it matters
Gerrymandering can significantly impact election outcomes, influencing which party controls legislative bodies and, consequently, the laws that affect your investments and daily life.
