How the job fits this community
California’s congressional map for the 2026 ballot is Proposition 50 (AB 604), adopted by voters on 4 November 2025. The U.S. Supreme Court allowed the map in February 2026. Unless a later order says otherwise, Proposition 50 is the map — not the 2021 Citizens Redistricting Commission lines. Confirm on the California Secretary of State and the voter-status lookup. Look up the address.
The 28th is the west San Gabriel Valley: Pasadena, Alhambra, Monterey Park, Arcadia, San Gabriel, Altadena, South Pasadena, Temple City, Rosemead, La Cañada Flintridge, and Sierra Madre, plus Upland and Rancho Cucamonga pieces. Glendora and Monrovia are the 31st. Claremont is the 35th. Confirm the address.
Federal work here is a Pasadena inbox and a San-Gabriel-Valley inbox. Alhambra and Monterey Park file the west valley. Arcadia and San Gabriel file the middle. Staff who still file Glendora, Monrovia, or Claremont here are on the 2021 map.
The Representative is the human hinge between this Pasadena-and-Alhambra map and Washington.
What the job entails
- Legislate. Introduce and cosponsor bills. Sit on committees. Vote.
- The purse. The House originates revenue bills. Appropriations decide what actually gets built or staffed.
- Oversight. Hearings and letters that watch the executive branch.
- Casework. SSA, VA, IRS, USCIS, military records, passports.
- District presence. Town halls, city halls, employers, schools — the district is the employer.
- Two homes. Washington for votes and committees. The district for the people who hired the office.
What a day is like
There is no single Tuesday. In Washington: a visitor from Pasadena and a visitor from Alhambra. In the district: a Los Angeles desk and a San Bernardino desk.
The staff is the office. A serious Member is a serious principal: clear priorities, honest casework, no rumor as policy.
