3 predictions · 14 assertions · 2 opinions · 4 insights · 6 disclosures · every statement was checked. The predictions and assertions are the 17 claims: statements the public record can support or contradict. 6 are resolved, 2 are not yet assessed, and 9 name no date, number or outcome precise enough to check. Everything else (opinions, insights, what ifs, disclosures) can never be settled by the record, so it carries no assessment.
