Fact-Checked False Statements

The Washington Post Fact Checker database documented 30,573 false or misleading claims across Trump's first term (~21/day). It is real, sourced, itemized data. It is also the purest example in this whole project of a measurement that exists for one president and not the others, so the panel charts only the one window where the same instrument measured two presidents.

The only apples-to-apples window: first 100 days, same outlet, same methodology

Trump 2017

511

~5.1 claims/day over the first 100 days

Biden 2021

~0.8 claims/day over the first 100 days

Within the one directly comparable window, the same fact-checkers applying the same standard found roughly a 6.5× difference. Beyond that window, the instrument itself diverged: the Post ended Biden's database after 100 days, judging the volume didn't warrant the resource, while Trump's ran all four years and compounded, from ~5/day in year one to ~39/day in year four, totaling 30,573. That escalation curve is real and documented; it just has no measured counterpart to sit beside.

Why this is a caveat metric: a cross-president chart of full-term totals would compare a measured president against unmeasured ones, the exact asymmetric-data trap this project exists to avoid. The defensible claims are narrow: (1) in the only controlled comparison, Trump's rate was ~6.5× Biden's; (2) Trump's full-term total is documented and historically unprecedented as a measured object, no equivalent object exists for Clinton, Bush, or Obama, and its absence is not evidence of their honesty, only of unmeasurement. A skeptic's caveat also belongs on record: the decision to track one president intensively and stop tracking another is itself a judgment critics call bias and the Post calls triage; the 100-day window is the only place that dispute doesn't matter.
