Justin Levitt's study on voter impersonation from 2000 to 2014 suggests that this form of voter fraud is extremely rare in the United States. Out of over 1 billion votes cast during that period, Levitt found only 31 credible incidents of voter impersonation. This indicates that voter impersonation is statistically insignificant and challenges the notion that it is a widespread problem. Levitt's study emphasizes the importance of ensuring access to voting rights while maintaining safeguards to protect the integrity of the electoral process.
