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.
SMITH. Smith is commonly viewed as a centrist Democrat. GGUM places him near the left pole of the chamber, well to the left of his centrist reputation.
BACON. Bacon is commonly viewed as a bipartisan, centrist Republican. GGUM places him to the right of the chamber median, though well short of the right pole.
GRIFFITH. Griffith is commonly viewed as a mainstream conservative Republican. GGUM places him at the extreme-right pole.
