Nov. 6, 2026 — Tuesday’s general election dramatically reshaped control of Congress, and the blue tsunami proved to have a significant, if slightly less historic, effect at the state legislative level. According to results tallied as of Friday, nine states saw party control change in at least one chamber.
The most notable change came in Arizona. The historically purple-leaning-red state saw Democrats take sizable majorities in both the state House and the state Senate, with Democratic Gov. Katie Hobbs securing a second term in the executive branch.
For the past two years Arizona Republicans worked with a 33-27 majority in the state House and a 17-13 advantage in the state Senate. On Tuesday, Democrats flipped both chambers, winning party control along with the governorship for the first time in 60 years. Although votes in tight districts are still being counted, the AP on Friday called enough races for Democrats to win control of both chambers.
As it stands on Friday afternoon, Arizona Democrats are expected to finish with a 20-10 supermajority in the Senate and a 37-23 advantage in the House.
Map: Party control of state legislatures in 2027
Following Tuesday’s election, 22 states will have Republican party control of both legislative chambers, while Democrats will exercise dual-chamber control in 24 states. Four states will have split chambers. Nebraska has a unique unicameral (one chamber) system led by a Republican majority, while Alaska is led in both chambers by a coalition majority made up of both Republicans and Democrats.
330+ seats netted by Democrats across all state legislative races
Tuesday’s vote netted at least 330 state legislative seats for the Democrats, putting them in a position to pass legislation that would have been unheard of just one year ago.
Nine states saw a change in legislative control of at least one chamber. Democrats gained control of both chambers in Arizona, New Hampshire and Wisconsin, and of one chamber each in Georgia, Michigan, Minnesota, North Carolina, Pennsylvania, and Texas. Republicans did not flip any chambers.
The New York Times published this chart, below, on Wednesday morning as votes were still being counted. Since then, Arizona has been called for the Democrats, who will control the House, the Senate, and the Governor’s seat. The Georgia House has since been called for the Democrats, and the party has secured large majorities in both chambers in New Hampshire.
