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.
FEINGOLD. Feingold is commonly viewed as one of the most liberal members of the Senate. GGUM places him near the Senate center in this chamber, breaking his pattern in surrounding Congresses.
McCAIN. McCain is commonly viewed as a self-styled maverick and repeat cross-party dealmaker. GGUM places him among the twenty most conservative senators in this Congress.
