Widespread gerrymandering can affect both state and national policy by

Gerrymandering redraws voting districts to give one party an advantage, sometimes allowing it to win more seats than its share of the vote would suggest. When that advantage occurs in state legislative districts and congressional districts, the party is more likely to enact its platform in both state legislatures and the U.S. House of Representatives. Gerrymandering does not necessarily increase cooperation, turnout, or the number of laws passed.
