Michigan and Minnesota held elections for their lower, but not upper houses.https://ballotpedia.org/State_legislative_elections,_2004 State legislative elections, 2004 Six chambers in three territories and the District of Columbia were up as well. The 2004 elections created narrow legislative divisions across the country. Both parties flipped seats and chambers across the country, with most Democratic gains coming from the Northeast and West and most Republican gains coming from the South. Over 20 states featured statehouses controlled by fewer than four seats, and nearly 30 states featured divided governments. Both parties took advantage of heavy spending from 527 organizations.Prah Pamela M.

The institution of term limits contributed to the Republican takeover of the Oklahoma House of Representatives for the first time since 1923, and favorable redistricting aided Republicans in winning the Georgia House of Representatives (and a trifecta) for the first time ever. Republicans additionally won the Tennessee Senate, for the time since 1870, and the Indiana House of Representatives. Democrats performed better than Republicans overall at the state-legislative level, despite their defeat in the concurrent presidential election, winning control of eight additional chambers. Favorable redistricting enabled the Democratic takeover of the Montana Legislature and their retaking of control of the North Carolina House of Representatives, which was previously tied. Additionally, they took control of the Washington Senate; the Oregon Senate, which was previously tied; both houses of the Colorado General Assembly for the first time since 1963, and the Vermont House of Representatives. The Iowa Senate became tied after previously being controlled by the Republicans prior to the election.Madigan Erin Kelderman Eric November 5, 2004 GOP Loses Ground in Statehouse Control http://pew.org/1LCr5hr 2023-03-03 pew.org en Democrats' takeover of the Montana House only came after the Montana Supreme Court declared a Democrat a victor in a contested election that evenly split the chamber. This gave Democrats control of the chamber with the help of incoming governor Brian Schweitzer.Robbins Jim 2004-12-29 Ruling Puts Democrats in Control in Montana en-US The New York Times https://www.nytimes.com/2004/12/29/politics/ruling-puts-democrats-in-control-in-montana.html 2023-03-03 0362-4331 The Democrats also regained the title of holding the most legislative seats across the country, winning one more seat than the Republicans.Storey Tim 2005 2004 legislative elections https://link.gale.com/apps/doc/A130348327/AONE?u=txshracd2548 Spectrum: The Journal of State Government 78 1 8 Gale Academic OneFile Summary table Regularly scheduled elections were held in 85 of the 99 state legislative chambers in the United States. Nationwide, regularly scheduled elections were held for 6,015 of the 7,383 legislative seats. Many legislative chambers held elections for all seats, but some legislative chambers that use staggered elections held elections for only a portion of the total seats in the chamber. The chambers not up for election either hold regularly scheduled elections in odd-numbered years, or have four-year terms and hold all regularly scheduled elections in presidential midterm election years. Note that this table only covers regularly scheduled elections; additional special elections took place concurrently with these regularly scheduled elections.

The application of newly enacted term limits in some states was expected to have little effect, with the exception of the Oklahoma House of Representatives, and the close nature of the concurrent presidential election made the effects of potential presidential coattails difficult to predict.Jacobson Louis July 9, 2004 Handicapping the State Legislatures: A 50-State Preview https://dataverse.harvard.edu/dataset.xhtml?persistentId=doi:10.7910/DVN/EH6LU0 The Rothenberg Political Report 7–10 Harvard Dataverse As the election progressed and George W. Bush's chances at winning re-election appeared to increase, outlooks changed on very few legislative chambers. Republicans made minor inroads in states in the South, especially in Oklahoma in the Georgia House of Representatives while Democrats appeared stronger in states in the Northeast and Northwest, such as Vermont and Washington. Due to the presidential election's heavy focus on foreign policy issues such as the Iraq War, the likelihood of coattails reaching all the way down to state legislative races appeared increasingly thin. The majority of state legislative chambers and individual races also remained out of reach for opposition parties due to the prevalence of partisan gerrymandering.
