CA-45 is rated Lean D. Structural demographic shifts in Orange County's Asian-American community and college-educated suburbs make this seat increasingly difficult for Republicans to hold. A midterm environment favoring Democrats could produce a flip even without a particularly strong individual challenger. Full House overview →
The Candidates
Michelle Steel
Korean-American Republican first elected 2020. Former Orange County Board of Supervisors chair. Steel's own demographic background gives her some appeal among Asian-American voters, but demographic trends in the district are moving against her. She has worked to carve out some moderate positioning on certain issues.
Weaknesses: Lean D fundamentals, adverse demographic trend, Trump alignment.
Irvine-Area Democrat
Democrats will recruit a candidate with strong ties to the Irvine and Orange County Asian-American community. An Asian-American Democrat — particularly Korean-American or Chinese-American — would have maximal appeal in this electorate. Local city councilmembers, county officials, and community leaders are likely prospects.
Challenges: Steel's incumbency and her own Asian-American identity create a higher bar.
Key Facts — CA-45
District Election History
Race Analysis
The District: Orange County's Most Diverse Battleground
California's 45th congressional district covers the southern and inland portions of Orange County around Irvine — one of the most planned and prosperous cities in the United States. Irvine was deliberately designed around its relationship with UC Irvine and the tech and biomedical industries, and it has attracted a disproportionately high-educated, high-income, and notably diverse population. The district's Asian-American share — which includes major Korean, Chinese, Indian, and Vietnamese communities — is among the highest of any competitive House district in the country.
Michelle Steel's political identity is deeply intertwined with her Korean-American heritage, and she has represented Orange County's Korean-American community politically for decades through her work on the Board of Supervisors before entering Congress. That personal connection gives her some insulation from the broader Democratic shift among Asian-American voters. But the shift is real and significant: Korean-American and Chinese-American voters who once leaned Republican have been moving toward Democrats, driven by concerns about hate crimes against Asian Americans during and after the COVID-19 pandemic, healthcare policy, and the perception that the Republican Party's nationalist tone is exclusionary.
The housing affordability crisis is an acute issue in CA-45. Irvine and the surrounding communities are among the most expensive housing markets in California, which itself is one of the most expensive states in the nation. Young families and working professionals face enormous barriers to homeownership, and even high earners are cost-burdened by rent. This issue does not map neatly onto traditional partisan lines — both parties claim to have solutions — but Democrats who can credibly address supply-side housing reform while connecting it to federal policy will have a resonant message in this district.
Key Issues
Asian-American Voters
The large and politically active Asian-American electorate is the swing vote in CA-45. Korean and Chinese-American communities in particular have been trending Democratic. Candidate identity and ability to communicate with these communities in culturally resonant ways matters enormously.
Healthcare Policy
A large biomedical and healthcare industry employer base plus a well-educated population makes healthcare policy — including drug pricing, the ACA, and Medicaid — a high-salience issue. Any Republican votes against healthcare coverage will be heavily attacked in this district.
Housing Affordability
Southern California's housing crisis hits even high earners in CA-45. Home prices, rent costs, and the difficulty of family formation for professional households under 40 are central economic concerns. Federal housing policy and any signals on deregulation or housing investment will play politically.
What to Watch in 2026
- Democratic candidate identity: An Asian-American Democratic challenger — especially Korean or Chinese-American — would directly contest Steel's key political identity advantage. Candidate ethnicity and cultural fluency will matter more here than in almost any other district.
- Steel's positioning: Watch whether Steel tries to moderate her profile heading into 2026 or doubles down on MAGA alignment. Her ability to distance herself from unpopular national Republican positions will determine her ceiling.
- Asian-American community outreach: Turnout and mobilization among Korean, Chinese, and Vietnamese-American voters in the district will be closely watched by both campaigns. Whichever party invests more deeply in language-accessible outreach will have an organizational advantage.
- California redistricting fallout: Any changes to district lines before 2026 could alter the landscape. The current Lean D rating assumes roughly current boundaries.
