Drop boxes also are a focal point of the film “2,000 Mules,” which used a flawed analysis of cellphone location data and ballot drop box surveillance footage to cast doubt on the results of the 2020 presidential election.

In response to the legislation and conspiracy theories surrounding drop boxes, the AP sent a survey in May to the top elections office in each state seeking information about whether the boxes were tied to fraudulent votes or stolen ballots, or whether the boxes and the ballots they contained were damaged.

All but five states responded to the questions.

None of the election offices in states that allowed the use of drop boxes in 2020 reported any instances in which the boxes were connected to voter fraud or stolen ballots. Likewise, none reported incidents in which the boxes or ballots were damaged to the extent that election results would have been affected.
