    On February 18, 2022, the New Jersey Legislative Reapportionment Commission voted to approve a new set of state legislative maps.[1] The commission voted 9-2 to approve the maps. Thomas Kean Jr. (R) and Cosmo A. Cirillo (D) were the two dissenting votes.[2] The New Jersey Monitor's Nikita Biryukov wrote that the vote was "an unprecedented compromise for a commission that has historically relied on a court-appointed tiebreaker to end partisan gridlock."[1]
