Mixed-party election outcomes in presidential election years, 1916-2024
When there are multiple offices on the ballot, voters can choose candidates from different political parties for the various offices. This practice is known as split-ticket voting, and it can lead to a mixed-party election outcome, or a situation where a state elects a governor of one party and a U.S. senator of another party, or gives its electoral votes to the candidate of one political party while electing a state legislative majority of another party. Ballotpedia has previously published analysis of split-ticket voting in the 2024 elections at both the gubernatorial and statewide election levels.
For the purposes of this analysis, we defined a mixed-party election outcomes as one where the candidate of one party won the state’s presidential electoral votes while candidates of another party won a U.S. Senate seat, a majority of the state's U.S. House delegation, or a state legislative majority on the same ballot.[1] These outcomes have trended down since high-water marks in the 1980s. These outcomes nearly halved by the 1990s before falling into the single digits in the three presidential elections from 2016-2024. In their 2002 book Why Americans Split Their Tickets: Campaigns, Competition, and Divided Government, professors Barry Burden and David Kimball argued that two factors primarily drove split-ticket voting: lack of competition and well-funded incumbents in congressional elections and popular presidential candidates.[2]
From 1916 to 2024, 25.3% (1,179 of 4,651) of all possible mixed-party election outcomes occurred. The years with the most mixed-party election outcomes were 1984 (97 out of 166 possible, or 58.4%) and 1972 (86 out of 166, or 51.8%). Each of those years was one in which a presidential candidate won 49 states. The years with the mixed-party election outcomes was 1920, with seven out of a possible 163 (4.3%). Tied for second-fewest with nine were 2016 (nine out of 170 possible, or 5.3%) and 2024 (nine out of 168 possible, or 5.4%).
Oklahoma (43) led all states with the highest number of mixed-party election outcomes across this span, followed by Florida (42) and Tennessee (40). The states with the fewest number of mixed-party election outcomes were Nebraska and Hawaii, with six each. Nebraska, with only one legislative chamber, has fewer total opportunities for mixed-party election outcomes, while Hawaii became a state in 1959. The state with the fewest mixed-party election outcomes with two legislative chambers and statehood for the course of this analysis was Utah, with seven.
