Voter fraud is an umbrella term that can mean a lot of different things. A few examples include: illegal registering and voting by individuals who aren’t citizens; changing the actual vote count at a polling location; and stealing ballot boxes.

All of this has indeed happened in the past.

In 2015, it happened in Bloomingburg, when four people conspired to falsely register non-residents to vote in the village election. Their goal was to elect board members who would favor their planned housing development project.

But this kind of voter fraud is not systematic. One database, created by the conservative Heritage Foundation, which tracks voter fraud, found fewer than 1,300 proven cases of voter fraud have taken place in the U.S. since 1982.

The Brennan Center for Justice at NYU School of Law has compiled a compendium of research from all over the political spectrum that disputes the idea that there is, or will be, widespread voter fraud in the U.S. Michael Waldman, the president of the Brennan Center, spoke with Capital Tonight host Susan Arbetter about the issue.
