New Hampshire enacted the final congressional map of the 2020 redistricting cycle on May 31, 2022, when the New Hampshire Supreme Court approved a map drawn by redistricting special master Nathaniel Persily. New Hampshire was apportioned two seats in the U.S. House of Representatives after the 2020 census, one more than it received after the 2010 census. This map will take effect for New Hampshire’s 2022 congressional elections.
The New Hampshire Supreme Court assumed control over the redistricting process as part of a lawsuit filed by former New Hampshire House Speaker Terie Norelli (D) and several voters. On April 11, the court announced it would take control of the process if the state legislature and governor could not draw a new congressional map.
The New Hampshire state legislature approved two congressional map bills. The first was approved 186-164 in the New Hampshire House on January 5 and 13-11 in the New Hampshire Senate on March 17. Shortly after the map was approved by the Senate, Gov. Chris Sununu (R) said he planned to veto the map. The House voted 176-171 and the Senate voted 14-10 to approve a second map bill on May 26. On the same day, Sununu said he planned to veto the map.
As of May 31, 43 states have adopted new congressional maps, six states were apportioned one congressional district (so no congressional redistricting is required), and Florida’s congressional map is currently undergoing a legal challenge. As of May 31 in 2012, 42 states had enacted congressional redistricting plans.
States have completed congressional redistricting for 408 of the 435 seats (93.8%) in the U.S. House of Representatives.
