Tusk Holdings CEO Bradley Tusk talks with Recode's Kara Swisher about his unique political consulting firm Tusk Ventures, which trades equity in companies like Uber, FanDuel and DraftKings for regulatory guidance. Tusk previously worked for former New York City mayor Michael Bloomberg, and explains in detail how Uber undermined the city's current mayor, Bill de Blasio, with a series of blistering attacks last year. He also talks about the tech challenges facing America's next president, including autonomous driving, drone regulation and how sharing-economy workers are classified.
