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.

Research notes & limits

Federal key votes and FEC finance totals for incumbent Boebert are added separately by script. Douglas Mangeris (Libertarian) has no discoverable public statements beyond the Ballotpedia ballot listing; write-in Republican candidate Luis Galvan is omitted as not having a documented active campaign. Biography gaps: no personal or career details found for Douglas Mangeris beyond his Libertarian nomination; Boebert's house.gov biography could not be fetched (403), so her biography relies on Ballotpedia.
