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 Ohio during Portman’s time representing it (2011 to 2023). It does not say what the member did or caused. It is not a score, and PORKER never ranks members on it.

Ohio’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.
