Is Non-Citizen Voting a Real Threat to Elections in Wisconsin?
Out of 68 cases of election fraud in Wisconsin listed in the Heritage database, only one involved an immigrant, for a rate of 1.5%. If the whole nation is included in the calculation, there were 1,620 cases of election fraud, 80 of which involved an immigrant, or 4.9% of the total number of election fraud cases.
There were numerous other efforts to estimate the rate of immigrants trying to vote, all of which lead to the conclusion that the rate is infinitesimal. Ironically, one such analysis was undertaken by the Trump administration to support his contention that illegal voting by undocumented immigrants is a rampant and insidious threat.
According to a recent article in The New York Times, Homeland Security Investigations, part of Immigration and Customs Enforcement, recently sent a memo requiring its employees to review all open and closed voter fraud cases involving immigrants who registered to vote, or actually voted, before they became naturalized U.S. citizens.
The Times reported that out of 49.5 million voter registrations, about 10,000 were referred to Homeland Security Investigations for further investigation, roughly 0.02 percent of the names processed.
