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.

Recent votes

No recorded roll-call votes in PORKER’s records. Roll-call records start in 2011.

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 Massachusetts during Delahunt’s time representing it (1997 to 2011). It does not say what the member did or caused. It is not a score, and PORKER never ranks members on it.

Survey years start at 2005. The yearly estimates for Massachusetts begin in 2005, so 1997 to 2004 are not shown. No 2020 yearly estimate exists.

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.
