Issue evidence — side by side
Recorded votes, documented positions and candidates’ own words are shown with sources. “In their own words” quotes a candidate on the topic without inferring a stance. Votes describe specific bills or motions; they do not establish overall support or opposition to a broad issue. A dash means our research has no evidence on that topic, not that the candidate has no position.
