You happen to be rational and you use the brain that God gave you to recognize that there is not a single source out there that is perfectly unbiased and pure on it's reporting. This is unlike several people on here (looking at you Jimbo) who laughable bashes every source that is presented to them as an "armpit" or some other body part unless it is Fox, Breitbart, etc.Anyway, a couple of things about PolitiFact. They have been admittedly subjective and have admitted in part that their Truth-O-Meter is arbitrary.
I have used PolitiFact for my own personal research; but I would never appeal to them as the end all, be all. To me, they are no different than other sources. One isn’t dismissing the truth by dismissing them.
At least they are consistent in their ignorance.
