Source: MIT Election Data and Science Lab, U.S. House V15 / U.S. Senate V8 (CC0), retrieved 2026-10-18; winners matched to member records by seat and term. Results run through the 2024 elections; nothing from 2026 is shown until it is certified. A margin is a fact about one election, never a score of how well a member represents anyone, and PORKER does not rank members by it.
How has Illinois done while Sen. Kirk served?
2010 to 2016 in Illinois: typical household income was up 4% after inflation, the share of people below the poverty line was down 0.8 points, and the share of workers looking for a job was down 5.1 points.
Each mini chart has its own scale, fitted to its lines (it does not start at zero), so compare the numbers, not the heights. Oxblood = state, grey = U.S.
While they served, not because of them. This shows what happened in Illinois during Kirk’s time representing it (2010 to 2017). It does not say what the member did or caused. It is not a score, and PORKER never ranks members on it.
Illinois’s borders do not change, so every year is comparable. The Census Bureau has no 2020 yearly estimate.

Read this first. These are counts of records Congress.gov lists. Many bills never get a CBO estimate or a report, so a zero is not a mark against a member. We never show this as a score.
