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.
CARPER. Carper is commonly viewed as one of the Senate’s most consistently cited centrist/moderate Democrats. GGUM places him solidly within the chamber’s progressive range.
BOOZMAN. Boozman is commonly viewed as a quiet, standard-conservative Arkansas senator, not a national ideologue. GGUM places him among the chamber’s most extreme conservatives.
