the most unfathomable U.S. presidentail race in memory gave Predata, a startup firm backed by hedge fund manager kyle Bass, a chance to cut through the vitriol and coolly calculate the winner by monitoring chat data. urns out that Predata, which anointed Hillary Clinton the likely victor days before the Nov.8 vote, was no smarter than the cable news pundits.
