If PolitiFact's big mistakes tend to harm Republicans and not Democrats, it's a pretty good sign that PolitiFact leans left. For that reason, much of what we do centers on documenting big mistakes.
Veteran PolitiFact fact checker Louis Jacobson gave us a whopper of a mistake this week in a Sept. 12, 2018 PunditFact fact check.
We easily found a parallel claim, this one from PolitiFact Virginia but with Trump as the speaker:
A Meaningless Statistic?Scarborough's statistic makes less sense than Trump's on closer examination. The point comes through clearly once we see how PolitiFact botched its analysis.
Scarborough said the GOP would create more debt in one year than was generated in America's first 200 years.
After quoting an expert who said percentage of GDP serves as a better measure than nominal dollars, PolitiFact proceeded to explain that testing Scarborough's claim using the percentage of GDP tells essentially the same story. PolitiFact shared a chart based on data from the executive branch's Office of Management and Budget:
So far so good. The OMB is recognized as a solid source for such data. But then PolitiFact PolitiSplains (bold emphasis added):
The chart does show that, when looking at a percentage of GDP, Scarborough is correct in his comparison. Debt as a percentage of GDP in 2017 was far higher (almost 77 percent) than it was in 1976 (about 27 percent).Colossal Blunder Alert!
PolitiFact/PunditFact, intentionally or otherwise, pulled a bait and switch. Scarborough said the GOP would create more debt in one year than was generated in America's first 200 years. As PolitiFact recognized when comparing the nominal dollar figures, that comparison involves the cumulative deficit number for one year (which we call the debt) and comparing it to the non-cumulative deficit number for one year (which we call the deficit). It's a comparison of the debt in 1976, following PolitiFact's methodology for nominal dollars in the first part of the fact check, to the deficit for 2017.
But that's not what PolitiFact did when it tried to test Scarborough using percentage of GDP.
PolitiFact compared the debt in 1976 to the debt in 2017. That's the wrong comparison. PolitiFact needed to substitute the deficit in 2017 as a percentage of GDP for the debt in 2017 as a percentage of GDP. That substitution corresponds to Scarborough's argument.
The deficit in 2017 does not measure out to nearly 77 percent of GDP. Not even close.
The OMB reports the deficit for 2017 was 3.5 percent of GDP. That's less than 27 percent. It's also less than 77 percent.
Using the preferred measure for comparing deficit and debt numbers across time, Scarborough's claim fell flat. And PolitiFact failed to notice.
Testing Scarborough's number correctly as a percentage of GDP illustrates the worthlessless of his statistic. Instead of "Mostly True" PolitiFact could easily have issued a ruling more similar to the one it issued to Republican presidential candidate Mitt Romney when he correctly noted that our armed forces were shorter on ships and planes in 2012 than at times in the past.
Cheer up, PolitiFact. You'll be tarring the conservative Scarborough. So it's not a total loss.
