… When Paul Manafort allegedly shared “polling data” with Konstantin V. Kilimnik, a Russian businessman and former military interpreter who the FBI says has “ties to a Russian intelligence service,” many Americans may have shrugged and thought “so what?” To them, polling data is the result of simple surveys that tell us “52 percent of people favor Candidate A,” or “72 percent of Democrats oppose Policy B.” It’s not. It’s far more detailed, and the way advertisers and political campaigns use it has serious consequences. CONT.
