"I know it sounds creepy, but a lot of people are skeptical about the election process, thinking that there are voters who are no longer alive and still on the ballot. We need to be careful," said Tonnie Adams, supervisor of elections in Heard County, a battleground state in Georgia.

Every day, Tonnie Adams had to comb local funeral home websites, read every obituary in the newspaper and write down the names of the deceased, removing them from the voter rolls.

Although cases of voter fraud using dead people's names to vote are rare, US election officials are particularly vigilant because the entire voting process is closely monitored by the public.

Many states require public voter lists so that people can monitor and detect irregularities in the voting process, especially in the seven battleground states that are considered to be the places that decide the outcome.

During the 2020 election, former President Donald Trump claimed that thousands of "dead voters" still voted for president, raising suspicions of election fraud, although without basis.
