Bradley Tusk has a plan to fix American democracy. A former high-level staffer for Chuck Schumer and Michael Bloomberg, among others, Tusk has recently been using his political wits to help tech companies sidestep red tape and clear regulatory hurdles. As he recounts in his new book, “The Fixer: My Adventures Saving Startups from Death by Politics,” Tusk has—for better or for worse—convinced authorities across the country to let Uber operate in their cities, figured out how to get the San Jose City Council to allow on-demand home delivery for marijuana, and toppled regulations banning the sale of online homeowners and renters’ insurance. When Uber, the first tech client of his fledgling consulting firm, didn’t have enough cash to pay him, Tusk took half his compensation in equity. As a consequence, he said, “I just got more money than I ever expected to have.” … On its face, voting by phone makes sense. Nearly ninety-five per cent of American adults own mobile phones, and rely on them for all sorts of secure transactions. Using them to cast a ballot would seem to be a natural extension, and one that removes many of the impediments that discourage people from voting, such as inconveniently located polling places, limited hours, and long lines. A survey of 3,649 voting-age Americans in 2016 found that about forty per cent would choose the option of Internet voting if it were offered. (Voting by phone app is a variant of Internet voting, since ballots are transmitted over the Internet.) But implementing a working system is not as simple as it may appear.
