There's consistently a lot of shock and outrage about foreign interference in American elections, however there seems to be no feasible solutions to the problem. If, as people seem to be doing, "election interference" doesn't mean hacked voting machines but 'hacked voters' (exposure to subversive foreign propaganda), then there is no defense against it without going to what we would consider a repressive state. Low-cost social-media memes, groups, and bot-comments are a super-weapon that can be deployed against any government that purports to be 'democratic' in its methods.

At a minimum, to actually combat 'foreign interference in elections,' the US would need to: - rigorously require anyone paying for political ads on social media to be US citizens, - require anyone posting comments on US-visible political social media topics to also be US citizens, - limit the exposure of US citizens to foreign media, both state-sponsored and 'private' - place additional surveillance or suspicion on first/second-generation immigrants who may be spreading latent ideological memes from foreign governments

In short, a China model rather than a traditionally Western model. In a globalized society with such free flow of information, is it even possible to have a national democracy that doesn't implicitly give the rest of a world voting access through rival-state mechanisms?
