How do we calculate my vote power?
What goes into the rating: Representation: how much weight one vote carries here compared with a statewide vote — the smaller the district, the more each vote counts. Decisiveness: how likely this race is to be close, based on past results or current analyst ratings, plus the number of candidates.
Representation: High · 68 out of 100
This district is a small slice of its state, so each vote here carries much more weight than a vote in a statewide race. About 748,393 people live here.
Show the representation math
score = 50 + 50 × ln(state population ÷ this district's) ÷ ln(50,000) = 50 + 50 × ln(39,287,377 ÷ 748,393) ÷ ln(50,000) = 68.3, measured against a statewide vote in CA (grades: 66+ high, 55+ above average, 33+ average, otherwise low; a statewide race is the 50 baseline)
Decisiveness: Low · rated not competitive as of August 20, 2026
Election analysts currently rate this race not competitive. Rating from Inside Elections.
Show the decisiveness math
IE "Solid Democrat" (d=5) → mean 5 → "not competitive" → grade low (d: toss-up 0, tilt 2, lean(s) 3, likely 4, solid/safe 5; mean, first match: <1 toss-up, <2.5 very competitive, <3.5 competitive, <4.5 somewhat competitive, otherwise not competitive; toss-up and very competitive grade high, competitive and somewhat competitive grade average, not competitive grades low)
High representation + low decisiveness → My vote power: Average.
The current race rating comes from a single analyst source, so it is less certain.
