5 predictions · 18 assertions · 4 disclosures · every statement was checked. The predictions and assertions are the 23 claims: statements the public record can support or contradict. 12 are resolved, 4 are not yet assessed, and 7 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.

How they sound: not measured why? →

We measure speaking style by listening to the audio itself, and a fair number needs at least 2,000 words from one person on tape we have measured. There is too little of Alex Immerman on measured tape to publish a rate. This says nothing about how they speak.
