Someone — the Russian military, say many cyberexperts — broke into the computers of the Democratic National Committee and the Democratic Congressional Campaign Committee, releasing emails and sensitive documents. Sounds bad, and is. But a worse danger looms: the possibility that hackers (whether Russians or others) will manipulate our voting machines, casting doubt on the election's outcome.
Imagine. It's the day after the election. Either Hillary Clinton or Donald Trump has "won." But the victor's triumph rests on close results in five or six states, where the winner had a few thousand more votes. Assume also that each of these states used — at least partially — electronic voting. Assume then that the loser alleges that cybertampering stole the election.
The resulting furor would be unavoidable. It would raise partisan anger still further. It would subvert faith in our basic democratic institutions and, probably, excite all manner of conspiracy theories. It would make the combat of the Bush-Gore election in 2000 — the disputes over which of Florida's "hanging chads" should be counted — look like child's play. It would be a disaster.
