The furor over the cyberattacks injecting turmoil into Hillary Clinton’s presidential campaign obscures a more pervasive danger to the U.S. political process: Much of it has only lax security against hackers, with few if any federal cops on the beat. No one regulator is responsible for requiring campaigns, political operations and state and local agencies to protect the sanctity of the voter rolls, voters’ personal data, donors’ financial information or even the election outcomes themselves. And as the Democrats saw in Philadelphia this past week, the result can be chaos. The most extreme danger, of course, is that cyber intruders could hack the voting machinery to pick winners and losers. But even less-ambitious exploits could sway the results in a close election — anything from tampering with parties’ volunteer schedules and get-out-the-vote operations to deleting the registrations of frequent voters or knocking registration databases offline. Cyber scams aimed at campaign donors’ financial data, such as a just-disclosed hack aimed at the Democratic Congressional Campaign Committee, could deter future contributors by making them fear identity theft. Or, as happened this past week to the Democratic National Committee, online thieves could get hold of a political operation’s embarrassing internal emails, creating headaches for a presidential candidate just before she accepts her party’s nomination.
