According to March’s partisan count of the 7,383 state legislators across the United States, 54.27% of all state legislators are Republicans, and 44.91% are Democrats.
Ballotpedia tallies the partisan balance of state legislatures, or which political party holds the majority of the seats in each chamber, at the end of every month. Republicans control 61 chambers, while Democrats control 37. One chamber (Alaska’s state House) has a power-sharing agreement between the two parties.
Republicans held 1,089 of the 1,972 total state senate seats—up five seats from February—and 2,918 of the total 5,411 state house seats—up one seat from last month. Democrats held 869 state senate seats (up three seats) and 2,447 state house seats (down two seats). Independent or third-party legislators held 38 seats. There were 22 vacant seats.
In March, Democrats saw a net increase of one seat, while Republicans saw a net increase of five seats. Compared to March 2020, Democrats have lost five state Senate seats (874 v. 869) and 139 state House seats (2,586 v. 2,447). Republicans have gained four state Senate seats (1,085 v 1,089) and 139 state House seats (2,779 v 2,918).
