State Senator District 5

August 4, 2026 · State Senate District 5; Michigan · State senate district · primary

Vote impact: High
How do we calculate vote impact?

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: High · 75 out of 100

Smaller districts give each vote more weight, and this district is small for its type. About 258,146 people live here.

score = 100 × ln(largest population ÷ this district's) ÷ ln(largest ÷ smallest), rounded to 2 decimals = 100 × ln(274,056 ÷ 258,146) ÷ ln(274,056 ÷ 253,220) = 75.63, comparing state senate districts in MI (grades: 66+ high, 33+ average, otherwise low)
