How to read this

Each criterion is scored 0 to 4 against the written rubric in the Ballot Standard. NR means no record: there is no reliable public evidence either way, so the criterion is left out and never counts against the candidate. A total is published when at least 8 of 15 criteria have evidence.

A sitting officeholder has a longer public record than a first-time candidate, so the two totals rest on different amounts of evidence. Read the count of criteria beside each score. Low marks require an official finding or a primary record. Allegations and opinion are not used.

No policy position is scored. Evidence checked October 9, 2026. Campaigns and readers can send a correction with a public source to tpg@thepoliticalgroup.com.
