Sparse Voter-Fraud Cases Undercut Claims of Widespread Abuses

Prosecutors across the country found evidence of voter fraud compelling enough to take to court about 200 times since the November 2018 elections, according to a 50-state Bloomberg canvass of state officials.

Republican and Democratic election and law enforcement officials contacted in 23 of the states were unable to point to any criminal voting fraud prosecutions since the November 2018 midterm elections.

Republicans hold 26 state attorneys general posts and control 28 secretary of state offices. The states controlled by Republicans in both of those offices reported roughly 59 prosecutions in their states during this period.

Democrats reported 102 prosecutions in the states where they held both of those offices. States where control between these offices is split between Republicans and Democrats—Arizona, Iowa, Maryland, Nevada, and New Hampshire—accounted for 35 prosecutions.
