USA election topology

About 500,000 official hosts. Layer 2 is the 365,076 voting systems states deployed for the 2024 general (EAVS: 224,945 ballot-marking devices, 26,257 paper-trail DREs, scanners at 28.3%, about 103,000, and a residual of DREs with no paper trail) plus about 7,500 election-management workstations. Layer 3 is about 110,000 e-pollbooks, about 250 voter-file servers, about 13,000 county registration clients, and about 3,000 office routers. Layer 4 is listeners only: online registration, night reporting, mail tracking, pollbook vendor APIs, and SAVE. Applications are deployments, not a second copy of the devices. One state EMS can be a single application on several workstations. A pollbook deployment is one per jurisdiction, not one per tablet. Spares left in storage are not included.

Campaign products on this map: about 20 (seven warehouses, Campaign Brain, iKE, VAN and MiniVAN, list tools, and the ad-graph platforms). Record counts are not hosts. Server counts are not public, so they are not in the totals.
