Zombie voters have been cited among the many reasons the Donald Trump campaign believe the US Presidential election was stolen from them.

From beyond the grave, it is said, they rose and cast ballots for Joe Biden.

Or possibly fraudulent ballots were cast in the names of people who have sadly passed away.

There is no evidence that any dead people voted in the US election.

In fact, CNN looked into a list of 14,000 names posted online of people in Michigan who it's claimed backed Biden from the beyond.

They checked 50 names from the list - the first 25, plus 25 chosen at random.

Of those, 37 were indeed dead, but had not voted.

Five had voted, but were still alive.

The remaining eight were alive, but had not voted.

It follows a string of viral videos where names of dead people - or people whose birthdays are more than 100 years ago - are entered into voting databases to reveal they had cast ballots.

But these instances have been debunked - and were usually down to a father and son having the same name and address, or clerical errors when recording a person's date of birth.

In some cases, officials use the date of January 1, 1900 as a placeholder for postal ballots where the date of birth was not filled in - making the voter appear on databases to be more than 120 years old.

On incredibly rare occasions, family members have cast postal ballots on behalf of relatives who had recently died.

But Justin Levitt, a law professor at Loyola Law School and a voter fraud expert told FactCheck.org : "Yes, every once in a while, it turns out that someone votes in the name of someone who’s passed away.

"A handful of votes in a sea of millions. It’s not OK, but it doesn’t swing results.”
