$0Pork: own shareFY2024 earmarks: none on record

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.

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.

2023 to 2024 in MT-2: typical household income was up 7% after inflation, the share of people below the poverty line was down 1.6 points, and the share of workers looking for a job was about the same.

Each mini chart has its own scale, fitted to its lines (it does not start at zero), so compare the numbers, not the heights. Teal = district, oxblood = state, grey = U.S.

While they served, not because of them. This shows what happened in Montana’s 2nd district during Rosendale’s time representing it (2023 to 2025). It does not say what the member did or caused. It is not a score, and PORKER never ranks members on it.

One set of district lines. MT-2 was redrawn in 2022 (the survey year the new lines first appear), but every survey year in Rosendale’s term so far (2023 and 2024) uses the same lines, so they can be compared. 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.
