How we count: “Broke with party” is a yes/no roll call where the member voted against most of their own party on that vote (party as recorded; even splits not counted). “Pork: own share” splits each earmark shared by several members evenly among them.

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.

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 Georgia during Isakson’s time representing it (2005 to 2019). It does not say what the member did or caused. It is not a score, and PORKER never ranks members on it.

Georgia’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.
