State Senator, District 13
November 3, 2026 · State Senate District 13; Texas · State senate district · general
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 · 68 out of 100
Smaller districts give each vote more weight, and this district is small for its type. About 952,807 people live here.
score = 100 × ln(largest population ÷ this district's) ÷ ln(largest ÷ smallest), rounded to 2 decimals = 100 × ln(1,056,826 ÷ 952,807) ÷ ln(1,056,826 ÷ 909,299) = 68.91, comparing state senate districts in TX (grades: 66+ high, 33+ average, otherwise low)
Decisiveness: None · only 1 candidate
One candidate is running unopposed, so votes can't change the outcome.
High representation + an uncontested race → Below average vote impact.
