We only wish we had the time and money needed to document as much as 10 percent of PolitiFact's flawed and biased work.
We've documented a number of times PolitiFact's penchant for ignoring its central principle for grading numbers claims. PolitiFact's founding editor Bill Adair declared that the most important part of a numbers claim is its underlying point. But PolitiFact will ignore the underlying point at the drop of a hat if it will benefit a Democrat.
Newsom vs Haley
Newsom and "per capita" interstate migration
Democratic governor Gavin Newsom, defending himself from the charge that California is losing population while Florida gains population, said "Per capita, more Floridians move to California than Californian's moving to Florida." PolitiFact rated the claim "Mostly True."
Experts gave varying answers about whether the margin was statistically significant, but they agreed that the slim differences make this argument technical, and not necessarily meaningful.
Haley and ship counts as a measure of military strength
Numerically, she’s on target with both countries’ ship counts. But experts say that simply counting ships omits context about a country’s true military capabilities.
Ship counts ignore overall ship size, specific warfighting capabilities, and overall geographic reach, all of which are metrics where the United States maintains an edge over China.
