The way I look at it is, Cambridge Analytica is the canary in the coal mine. Cambridge Analytica is the beginning; it's not the end. What CA has exposed is how easy it is to misappropriate information, take funds from mysterious sources, and then go and interfere in elections, particularly in cyberspace. What it really shows is how the Internet and the growing digitization of society have opened up vulnerabilities in our election system.
Elections, historically, feel like a very domestic, insulated activity, because previously, if you were a foreign actor, you would have to physically come to a country to interfere. Now you don't. I think, moving forward, we need to look at cybersecurity as a priority for elections, and we have to understand that we may look at social media as domestic political players, as a communication space, as scoring points, or for messaging.
If you are a malicious foreign actor, you look at it as an information battlefield. You don't look at these people as voters; you look at them very much as targets for manipulation and targets for division. This is why transparency mechanisms or requirements for online platforms that do any advertising in the political space would be a really helpful first step. That would make it a lot more difficult for a country like Russia to start to interfere in elections, if it has to be done in public.
