Toplines

Iowa

U.S. House

Iowa will maintain its current level of women’s representation in the U.S. House, with both (2R) incumbent women favored to win re-election in all-woman general election contests.

Montana

U.S. House 

Montana is likely to remain a state that has no women representing them in the U.S. Congress, as the sole woman nominee for U.S. House will challenge an incumbent in a contest where the incumbent is favored. No woman has served in Congress from Montana since 1943 when Jeanette Rankin, the first woman in history to serve in the U.S. Congress, left office.

Statewide Executive 

Women are all but assured to maintain their current level of representation (three offices) among Montana’s statewide elective executive officeholders. Incumbents Lieutenant Governor Kristen Juras (R) and Secretary of State Christi Jacobsen (R) are favored to win re-election, and a new woman will win the all-woman contest for superintendent of public instruction, replacing outgoing incumbent Elsie Arntzen (R), who was defeated in her bid for the U.S. House. 

New Jersey 

U.S. House

New Jersey could increase its level of women’s representation in the U.S. House. Both (2D) incumbent women are favored to win re-election, and Sue Altman (D) is the Democratic nominee in New Jersey’s 7th Congressional District, where she will challenge incumbent U.S. Representative Tom Kean, Jr. in a contest that Cook Political Report currently rates as a toss-up. No more than two women have served simultaneously in New Jersey’s congressional delegation. 

U.S. Senate

In New Jersey, neither woman major-party candidate for the U.S. Senate was successful, ensuring that New Jersey remains a state that has never sent a woman to the U.S. Senate. 

New Mexico

U.S. House

Women are the majority (66.7%) of major-party nominees for U.S. House in New Mexico and could increase their representation by one in election 2024 to become an all-woman U.S. House delegation. Both (2D) incumbent women are favored to win re-election, and former U.S. Representative Yvette Herrell (R) will challenge incumbent U.S. Representative Gabe Vazquez (D) in a contest that Cook Political Report currently rates as a toss-up. New Mexico formerly sent an all-woman delegation to the U.S. House in 2021, where three women served simultaneously through January 3, 2023.

U.S. Senate

Nella Domenici (R) – daughter of former U.S. Senator Pete Domenici (R-NM) – has secured the Republican nomination for U.S. Senate in New Mexico, where she will challenge incumbent Senator Martin Heinrich (D) in a contest currently rated as “Solid Democrat” by Cook Political Report. If successful in November, Domenici would be the first woman to serve in the U.S. Senate from New Mexico and the second woman senator to hold the same office as her father. 

South Dakota

U.S. House

South Dakota is likely to remain a state that has no women representing them in the U.S. Congress, as the sole woman nominee for U.S. House will challenge an incumbent in a contest where the incumbent is favored. No woman has served in Congress from South Dakota since 2019.
