Due to the repeated exposure effect in marketing, it might be a good idea to follow up on John Oliver pieces (or other popular pieces that are potentially high leverage) with easily shareable via social networks infographics. Examples: Civil Asset Forfeiture, Criminal Justice Reform, Municipal Violations, etc. The nice things about topics like these is that they have some headline stats that are inflammatory and attention getting. Like how badly the US is doing relative to insert developing country or how many people are getting screwed over. This should align with 538's incentives since creating these while the iron is still hot makes them more shareable.
