'Fact checking' by politics

The website carlyfiorina.org claims that Fiorina laid off 30,000 Hewlett-Packard employees and said she wished she had laid them off faster.

Despite this being a completely untrue statement, Politifact rated it as “half true” because 30,000 people were indeed laid off from HP.
...
In his ruling on the Fiorina statement, Jacobson wrote: “The claim is partially accurate, but takes some things out of context, so we rate it Half True.”

Now compare that reasoning to this one about Democratic presidential nominee Hillary Clinton and her foundation’s charitable spending: “The claim contains some element of truth but ignores critical facts that would give a different impression, so we rate it Mostly False.”
