Three independents caucus with the Democratic Party, and one other counts towards the Democratic majority for committee purposes.

Republicans have a 16-14 majority the state Senate and a 31-29 majority in the state House. The last time Democrats controlled either chamber of the Legislature was in 1992, when Democrats controlled the Senate. Because the governor is a Democrat, Arizona is one of 10 states with a divided. It has held this status since 2023 when Gov. Katie Hobbs (D) assumed office. Arizona's attorney general and secretary of state are also Democrats, meaning it has a Democratic triplex.
