State Governments
"The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people." — Tenth Amendment to the U.S. Constitution
States have broad powers to legislate certain aspects of life and society within their borders, wielding the power to do everything from levying taxes to setting highway speed limits. Political battles have long raged over how much power the Tenth Amendment should delegate to the states; some argue in favor of expanded federal powers, while others have gone so far as to call for a return of the confederation—a loose relationship between independent states rather than one unified country.
The legislative branch in each state largely mirrors the U.S. Congress, consisting of a lower chamber (the House) and an upper chamber (the Senate). The only exception to the rule is Nebraska, where the legislature is unicameral (single chamber) consisting of 33 members who call themselves senators.
Voters in each state elect a governor to oversee the executive branch. Every governor has the power to sign or veto the laws passed by their legislature. Vetoes (and veto overrides by the legislature) are common in states with divided government, where one party controls the legislature while the other party holds the governor's mansion.
There are 7,386 legislative seats spread among the 50 states. The largest chamber is New Hampshire House of Representatives, which has 400 members. The smallest chamber is the Alaska Senate, which has 20 members.
The following statistics represent the results of the 2024 general election, after which Republicans held 4,123 seats (55%), Democrats held 3,242 seats (44%), and third parties/independents held 21 seats (1%). Seat counts frequently change between elections as a result of resignations, deaths, and party switches.
Republicans held the governor's office in 27 states, while 23 states elected Democratic governors.
States where one party has control of the House, the Senate, and the governorship are called "trifectas." After the 2024 general elections, 24 states saw a Republican trifecta, 15 states had Democratic trifectas, and the remaining 11 states elected a divided government.
