In a significant upset, Democratic newcomer and Army veteran Derek Tran has defeated Republican incumbent Michelle Steel in California's 45th Congressional District. This victory marks a shift in the political landscape of a district that has leaned conservative but has increasingly become a battleground in recent elections. The Associated Press called the race for Tran.
The 45th District, encompassing areas of Orange County such as Fountain Valley, Westminster, and Garden Grove, has a large Asian American population. Tran's win over the Trump-endorsed Steel is a key victory for Democrats in a district that President Biden carried in 2020 by approximately 6 points. This district has seen recent volatility, with Democrat Katie Porter flipping it blue in 2018 before Steel reclaimed it for Republicans in 2020 and narrowly retained it in 2022.

Steel, who initially entered Congress in 2020 by winning the neighboring 48th District from incumbent Democrat Harley Rhouda, expressed gratitude for her time in office. In a post on X (formerly Twitter), she reflected on her service, emphasizing her commitment to assisting first-generation Americans and defending human rights. She thanked her supporters, staff, family, and volunteers, acknowledging the conclusion of this chapter and anticipating future endeavors.
