To clarify my reason for asking artursapek to explain - the tweet isn't a "hard and proven fact", it is a claim - albeit an implicit claim, but a claim nonetheless - as such, Politifact is evaluating the claim If artursapek disagrees with the analysis, he should either - explain why the Tweet is not a claim, or - explain why Politifact's evaluation of the claim is incorrect, misleading or otherwise wrong Otherwise, this is not an example of "a consistently liberal-biased source"
