When 650 thousand Tennesseans voted in the Memphis area, they probably didn’t expect their personal information would eventually be picked apart at a hacker conference at Caesars Palace Las Vegas.

The strength of the US voting system, according to former FBI director James Comey, is that it’s “clunky”—every state and often every district can choose its own setup and whether to use paper or electronic machines. And there are over a dozen different manufacturers supplying voting machines to electoral districts. While that clunkiness helps prevent large-scale voter hacking, it provides more opportunities for hackers to access polling data.
