How has Wyoming done while Sen. Lummis served?

2021 to 2024 in Wyoming: typical household income was about the same after inflation, the share of people below the poverty line was about the same, and the share of workers looking for a job was about the same.

Typical household income · after inflation

Wyoming: $75.6K in 2021 → $75.5K in 2024

Share of people below the poverty line

Share of workers looking for a job

Wyoming: 3.7% in 2021 → 3.4% in 2024

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 Wyoming during Lummis’s time representing it (2021 to now). It does not say what the member did or caused. It is not a score, and PORKER never ranks members on it.

Wyoming’s borders do not change, so every year is comparable. The Census Bureau has no 2020 yearly estimate.

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.
