CA-41 · MODEL v1.14 · 2 INPUTS MEASURED
CA-41 enters through the Republican-held flip route at 62.4. V0.9 replaces the flat 0.70 cap with the same partial-coverage rule the Democratic route uses: 65% of the route's evidence is available, so the weighted mean of 72.5 is scaled by 0.860, moving the score +11.2. V0.10 refreshes incumbent finance from the FEC candidate summary through 2026-06-30, moving the score -10.0 to 52.4.
THE MEMBER
Ken Calvert is the current Republican House member for CA-41. The retained congressional history records 33.5 cumulative years of House service through the source cutoff.

Not used in this route because the retained alignment trackers cover Democratic incumbents.
The FEC candidate summary snapshot (2026-06-30) reports $1,497,001 cash on hand, replacing the $262,136 release aggregate. The inverse log scale is 100 at $50,000 or less and 0 at $5 million or more.
Not in this score
No retained state-legislative Democratic primary catalog records uncontested contests for this state, so the component is omitted and the available weight is renormalized.
HOUSE HISTORY
Formula v0.9 Republican-held route: renormalized 0.45 × competitiveness + 0.20 × cash vulnerability + 0.15 × local context + 0.20 × state Democratic primary contestation (65% of component weight available) × 0.860 coverage multiplier; the former flat 0.70 cap is removed; v0.10 refreshes cash vulnerability from the FEC candidate summary snapshot
