Former member of Congress · last served 119th Congress
Markwayne Mullin
Markwayne Mullin was a Republican U.S. senator from Oklahoma, first elected to Congress in 2013, who voted with most Republicans on 99% of the 119th Congress’s yes/no votes and sponsored 5 bills that became law (113th–119th Congress).
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.

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 Oklahoma done while Sen. Mullin served?
2023 to 2024 in Oklahoma: typical household income was up 3% after inflation, the share of people below the poverty line was down 1.0 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. Oxblood = state, grey = U.S.
While they served, not because of them. This shows what happened in Oklahoma during Mullin’s time representing it (2023 to 2026). It does not say what the member did or caused. It is not a score, and PORKER never ranks members on it.
Oklahoma’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.

Evidence
- What is counted
- Senate roll calls in the 119th Congress on the question of confirming a civilian nomination, as recorded on senate.gov. Cloture and procedural votes are not counted.
- How it is matched
- The vote record names the nomination number; the senator is matched by the Senate member id.
- Not voting
- Includes absences and any other reason. The record does not say why.
589 of the 617 confirmed civilian nominations show a roll-call vote on their latest-action line; the rest show a voice vote, unanimous consent or another method, with no individual votes. So this is only the roll-call subset. It says nothing about whether any vote was right or wrong.
