Each kind of claim is scored on its own, out of 100: the share that held up, with the range it likely falls in. Fewer resolved claims give a wider range.

  • Factual claims

    Statements about the present or the past, checked against the record: did they hold up?

    80 72 88

    Medium confidence, 35 factual claims resolved. From 10 documents, 2014 to 2026; 15 documents sampled from 35 candidates found.

    Not scored: 46 unresolvable, 9 checkable only against their own records.
