"The tirade is amusing in that even while vilifying PolitiFact for shoddy journalism, Cruz gets his facts wrong, saying the Florida-based sleuths found one of his assertions to be "mostly false" when in fact the verdict was "half true." More important, it reflects the fact that the fact-checking movement, a relatively recent phenomenon, is becoming an essential part of our political landscape.
And thank goodness.
For too long, too much political journalism too often settled for reporting on an allegation, adding a denial from the other side and leaving things at that. That really doesn't help the reader, viewer or Web surfer too much.
What fact-checkers do is thoroughly investigate the pronouncements of the pols and reach judgments on their truth or falsity, judgments based, or certainly supposed to be based, not on the political orientation of the writer but on the facts he or she unearths."
