Now, many on both sides of the aisle are calling for states to expand mail-in voting and move toward all-mail elections.

President Trump has openly opposed mail-in voting, tweeting that it has "tremendous potential for voter fraud."

FactCheck.org's Robert Farley called Trump's claims "false," noting that there's "no evidence" proving widespread fraud.

In 2017, a Brennan Center for Justice study found that the rate of voter fraud in the US was between 0.00004% and 0.0009%.

It also has bipartisan support: Ohio's GOP legislature passed a bill making the state's primary an all-mail election.

Ohio Gov. Mike DeWine signed off on an all-mail primary in March. He told CNN that he "didn't really worry" about fraud.

Only five states in the country hold universal, all-mail elections: Colorado, Hawaii, Oregon, Utah and Washington.
