This election cycle, like many before it, the concept of voting machine hacking is going to be on people's minds. Though it's (probably) never happened, it is theoretically possible, and that's scary. Should people worry about their votes being stolen by hackers? (Donald Trump thinks so.) Or, should they be more afraid that the threat of hacking will keep voters away from the polls? (Many people are saying that's the real concern.) It's a lot to comprehend—so we asked Snowden and Star Trek Beyond star Zachary Quinto to help us explain it. Hey, if you need to worry about voter fraud, wouldn't you rather hear about it from someone as logical as Spock?
