As I noted over at Zebra Fact Check, PolitiFact is saying the people who decide a "Truth-O-Meter" rating have years of PolitiFact experience.
It doesn't appear true. In the past, PolitiFact admitted that state franchises were expected to supply their own board of editors to determine ratings, with PolitiFact supplying additional editors as needed.
It seems that's still the case. But where are the years of experience supposed to come from?
