There are 116 election jurisdictions in Missouri, each with their own voting system. That means there is no single voting system or single point of access.
Voting machines are not connected to the internet, so they can't be hacked from the internet.
Every single voting machine in Missouri is required to produce a paper audit trail.
When absentee ballots are processed, they are counted by a bipartisan team.
Voting machines are publicly tested both before and after election day.
Once checked for accuracy, election equipment is locked and sealed to prohibit any tampering with the equipment on election day.
All voting machines in Missouri are required to give the voter a second chance to ensure the ballot is marked correctly.
Election results are audited by local election officials before any results are certified.
In 2018, the Missouri Secretary of State's Office successfully obtained a federal grant in the amount of $7.2 million through the Help America Vote Act (HAVA). The office has laid the groundwork to spend those funds with local election authorities to improve both physical security and cyber security to further enhance the integrity of Missouri's election systems.
By law, Missouri's 116 local election authorities must canvass their respective voter rolls every two years, however the list-maintenance process goes far beyond these requirements. Election authorities receive regular reports from other state and federal agencies containing official data on eligible voters, such as voter and motor vehicle registrations, U.S. Postal Service address changes, and Social Security death records. Using these reports, our election authorities are able to keep voter rolls complete and up to date.
