On the ballot
- Young Kim — Republican
- Ken Calvert — Republican
This person holds your district's seat in the U.S. House of Representatives (2-year term).
Two sitting members of Congress are running against each other here, both Republicans, and it is the most expensive contest on this ballot at nearly $15 million combined. Ken Calvert led the June 2 primary with 34.9% and Young Kim took 20.6%. Kim currently represents this district; Calvert currently represents District 41 and moved here after Prop 50 redrew the congressional lines. The district covers part of Orange and Riverside counties.
The winner holds one of 435 seats in the U.S. House for a two-year term. A member introduces bills, sits on committees that shape federal legislation, votes on the federal budget and on war powers, and handles casework between constituents and federal agencies. Seniority governs committee standing — and this contest will end the career of one of two members who both currently hold it.
Redistricting created this race. Prop 50 redrew the lines and left two incumbents of the same party competing for one seat, so a sitting member of Congress will lose regardless of the outcome. Party offers no guidance here. The documented differences are tenure — 33 years against 5 — and legislative output, where the longer-serving member has 12 career laws to the newer member's 2, though the newer member has sponsored more bills this Congress.
Ken Calvert
Republican, a sitting member of Congress since 1993 who currently represents District 41 and is running here after Prop 50 redistricting. He has sponsored 33 bills in the 119th Congress, and 12 of his career bills have become law. He raised $6,142,469, of which $2,531,302 came from individuals.
Strengths
Thirty-three years of seniority and 12 career laws, plus a lead in the June primary despite not currently representing this district.
Trade-offs
He is asking voters who did not elect him to keep him in Congress ahead of the member they did elect.
Keep in mind
He led with 34.9%, well short of a majority, in a district that is new to him.
Young Kim
Republican, and the sitting member for this district since 2021. She has sponsored 53 bills in the 119th Congress — among the highest counts in the delegation — and 2 of her career bills have become law. She raised $8,837,239, the largest congressional campaign on this ballot after Ro Khanna's, of which $5,542,006 came from individuals.
Strengths
She is this district's current representative, has the highest bill count in this contest, and raised the larger campaign with 63% of it from named individuals.
Trade-offs
She finished 14 points behind in the primary despite incumbency and more money, and 2 career laws against her opponent's 12.
Keep in mind
Losing your own district's primary to a member from a neighbouring one is an unusual position for an incumbent going into November.
