Redistricting

See also: Redistricting in Indiana after the 2020 census

The Indiana General Assembly approved new state legislative district maps on October 1, 2021, and Gov. Eric Holcomb (R) signed the new district boundaries into law on October 4, 2021. The Indiana Senate Republican caucus released its first draft of state Senate districts on September 20, 2021, and the Indiana House Republican caucus released its first proposed state House district maps on September 14, 2021. The Indiana state Senate approved final legislative district boundaries by a vote of 36-12, with all votes to approve by Republicans. Eleven Senate Democrats joined State Sen. Ron Grooms (R) in voting against the maps. The Indiana House of Representatives approved final district maps by a vote of 64-25. All votes in favor were by Republicans with 22 Democrats and three Republicans voting against.[7][8]

After the General Assembly approved the maps, House Speaker Todd Huston said, "We're incredibly grateful for the work of Representative Greg Steuerwald and Senator Eric Koch who tirelessly and thoughtfully led the way on drawing these maps. Redistricting is a complex and important process that impacts all Hoosiers. We're thankful for the hundreds of constituents who shared their feedback along the way, and I'm confident we delivered fair maps that ensure every Hoosier vote counts."[9]

The full legislative history of Indiana's redistricting proposals, including House and Senate committee reports and proposed amendments, can be found here at the Indiana General Assembly's website. These maps took effect for Indiana's 2022 legislative elections.[10]

How does redistricting in Indiana work? In Indiana, the state legislature is responsible for drawing both congressional and state legislative district lines. The legislature must approve a redistricting plan by the close of the first legislative session occurring after completion of the United States Census. The governor may veto the lines drawn by the state legislature.[11][12]

In the event that both chambers of the state legislature do not approve a congressional redistricting plan, a backup commission must draw the lines. The commission comprises the following members:[12]

  1. Speaker of the House
  2. President Pro Tempore of the Senate
  3. Chair of the Elections Committee, Indiana State Senate
  4. Chair of the Elections and Apportionment Committee, Indiana House of Representatives
  5. A gubernatorial appointment

The Indiana Constitution mandates that state legislative districts be contiguous. There are no such requirements for congressional district lines.[11]
