Chuck Grassley
Placed from the roll-call score. Bioguide G000386.
Chuck Grassley is the Republican senator for the Senate from IA in the 119th Congress. The chart uses the October 2026 snapshot. The position is Voteview’s DW-NOMINATE score of the roll calls. Color is the party label. The place is the votes.
The first dimension is 0.363, drawn as economics +36. That is right of center on economics. The second dimension is -0.034, drawn as authority -3. The other axis sits near the middle. Voteview’s second dimension is not a pure social axis. The chart uses the public file anyway, rather than inventing a different number.
Inside the Senate, this first-dimension score ranks 52 of 100 from the left. The first-dimension score is left of the Republican median in this chamber (0.56). The nearest other Senate scores are Mitch McConnell (Republican, 0.402), Todd Young (Republican, 0.444), Thom Tillis (Republican, 0.388). Those names are neighbors on the scale, not a slate.
A short public-record note says: Iowa Republican. President pro tempore. The longest current Senate tenure. The score is the placement. The sentence only names what the record is already known for.
One left-to-right score cannot say how Chuck Grassley would vote on a single bill. The identity and the vote file can be checked at congress.gov through bioguide G000386.
