3 assertions · 8 insights · 2 disclosures · 1 what if · every statement was checked. The predictions and assertions are the 3 claims: statements the public record can support or contradict. 0 are resolved, and 3 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.

The record, in short

What the tape says about how Tim argues and how the claims held up. Everything they said, and everything said about them, is in the tabs below.
