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: Above average · 58 out of 100
