I can jump in on that. There are four things you can do right now before the end of the year to prepare for 2019.
One, aggressive political ad transparency should be applied by law on all of the platform companies.
Two, increase the amount of money and coordination of those who are monitoring and exposing foreign intervention directed at misinformation campaigns.
Third, elevate quickly a process for removing illegal content, with all of the proper caveats about free expression, so that we don't have to suffer from things that shouldn't be out there in the first place.
Fourth, start talking to young voters in the classroom. My kids are in this wonderful program in Canada called Student Vote. In it they do mock elections and learn about political parties and the political system. We should have a digital literacy component in that curriculum.
