July’s partisan count of the 7,383 state legislators across the United States shows 52.2% of all state legislators are Republicans and 47.0% are Democrats, which is consistent with previous months.
Ballotpedia also completes a count of the partisan balance of state legislatures at the end of every month. The partisan composition of state legislatures refers to which political party holds the majority of seats in the state senate and state house. Republicans hold a majority in 61 chambers, and Democrats hold the majority in 37 chambers. One chamber (Alaska’s state House) shares power between the two parties.
Altogether, there are 1,972 state senators and 5,411 state representatives. Republicans held 1,084 state senate seats–down two seats from June–and 2,770 state house seats–down six seats.
