Off-diagonal members
The following 4 members fall more than 2.5σ off the OLS fit of GGUM θ on W-NOMINATE dim-1. We flag these as diagnostic cases where the two scalings most disagree.
| Member | Party | State | nominate | GGUM θ | residual |
|---|---|---|---|---|---|
| HAWLEY | R | MO | +0.82 | +1.19 | -1.54 |
| MURPHY | D | CT | -0.29 | -3.54 | -1.25 |

Placements worth a second look
GGUM’s placement of the following members differs from what their established political reputations might lead a reader to expect. We draw attention to these cases so that researchers can consider them before using the estimates for a particular analysis; we are not alleging error.
HAWLEY. Hawley is commonly viewed as a strongly conservative Republican. GGUM places him toward the moderate end of the Republican range in this chamber, 6th-least-conservative of 54 Republicans.
MURPHY. Murphy is commonly viewed as a mainstream progressive. GGUM places him at the extreme-left pole in this chamber, 4th-most-left of 101 senators and essentially tied with Sanders and Warren.
