So the author bases his claim of bias on "if you're explaining, you're losing" and then takes 2,000 words to explain why he thinks Politifact is biased? That makes total sense.
Seriously, I see so many flaws with the argument. The first of which is that if Politifact is really trying to push a liberal agenda then they're really doing a crappy job of it by being biased for Jim Webb (a self-described conservative who refused to vote for Hillary but wouldn't say whether he voted for Trump). The second flaw is that they clearly show that Politifact rated Nancy Pelosi as the third most dishonest politician behind Trump and Cruz. Again, if they're so biased, why is Politifact trying to take down Pelosi? She's one of the most liberal members of Congress and a leader in the Democratic Party. They also rated Jeb Bush as one of the most honest politicians in the group, ahead of Joe Biden and Harry Reid. Also, why isn't John Kasich included in the analysis? Seems like a glaring omission to me.
The entire crux of the Federalist piece's argument relies on the fact that the average analysis of a Republican statement has more words than the average analysis of a Democrat's statement. That's a pretty thin thread on which to lay claim that Politifact is some left-wing propaganda machine. From the Federalist piece:
"When fact-checked by PolitiFact, Democrats had an average rating of 1.8, which is between “Mostly True” and “Half True.” The average Republican rating was 2.6, which is between “Half-True” and “Mostly False.” We also checked Republicans without President-elect Donald Trump in the mix and found that 0.8 truth gap narrowed to 0.5... All by himself, Trump has almost half of all the “Pants on Fire” ratings from the articles we scraped."
So by their own admission, Trump is responsible for a large part of the observed gap. It seems to me that the most likely explanation is that Donald Trump, Ted Cruz, and Nancy Pelosi are lying liars and that Kaine, Clinton, Obama, Sanders, and Jeb Bush lie too but not nearly as much.
But all of this is moot, because you've given two examples of so-called bias that were really just fuzzy areas of interpretation, and then you have refused to actually explain what it is you take issue with in those examples. I thought you were going to give me some glaring examples of where Politifact said that a liberal told the truth when it was clearly a lie or when a conservative was called a liar when they were clearly telling the truth. But it seems that your entire argument is based on the idea that they are slightly more generous to liberals, which again doesn't jibe with the data for Pelosi and Reid and it doesn't jibe with your example of Jim Webb.
