Personal information can be purchased to alter voter registrations in as many as 35 states, according to one Harvard study. Disinformation campaigns by other countries can confuse voters and manipulate public opinion.

Much of our democracy depends on eliminating these security issues in our voting system.

All 50 states have taken at least some steps to provide more election security, according to the Center for American Progress. Many have gotten help from the Department of Homeland Security or the National Guard to assess and identify some of the potential threats.

This list is based on a 2018 report by the Center for American Progress, an independent nonpartisan policy institute that seeks to improve life in America by developing new policy ideas, challenging the media to cover critical issues, and shape the national debate.

To grade each state's level of election security preparedness, CAP awarded points based on a state's adherence to a set of best practices included within each category. Categories include: minimum cybersecurity for voter registration systems, voter-verified paper audit trail, post-election audits, ballot accounting and reconciliation, paper absentee ballots, voting machine certification requirements, and pre-election logic and accuracy testing. The number of points in a category are translated as "good," "fair," "unsatisfactory" and "mixed."
