DHS policy on election/critical infrastructure

Statement by the former Secretary of the Dept. of Homeland Security (January, 6 2017):

"I have determined that election infrastructure in this country should be designated as a subsector of the existing Government Facilities critical infrastructure sector. Given the vital role elections play in this country, it is clear that certain systems and assets of election infrastructure meet the definition of critical infrastructure, in fact and in law. [...] By 'election infrastructure,' we mean storage facilities, polling places, and centralized vote tabulations locations used to support the election process, and information and communications technology to include voter registration databases, voting machines, and other systems to manage the election process and report and display results on behalf of state and local governments."

Also see this current DHS Secretary statement (7/16/18), which confirms that election systems are still considered critical infrastructure. If a foreign government attacks it then it's an act of war.
