Part 3: Mis/Disinformation Scenario Plans [no website available]
This section complements Part 1 and Part 2 of the Playbook and is available exclusively for election officials’ use. It provides specific recommendations and scenario-based materials to aid state and local election officials in building a response plan.
This guide includes materials for six mock scenarios that could occur and spread on social media: (1) false voter identification requirements spread online; (2) congestion is causing polling places to turn voters away; (3) political partisans are “stealing the election;” (4) the people who run elections are corrupt; (5) false claims that poll places are closed due to COVID-19; and (6) false claims of a judicial/official order to delay the election.
