Vote impact = representation (how much weight one vote carries here, the smaller the district's population, the higher the representation) + decisiveness (how likely this race is to be close, based on past results and number of candidates).

Representation: Average · 63 out of 100

This district is mid-sized for its type, so each vote carries average weight. About 260,707 people live here.
