BBC did a report on global voter fraud a while ago. #1 culprit; mail in ballots. Good luck finding that article today. It also talked about international inspectors but not in the US. Only in the "meager" countries...meh.
BBC articles are not deleted, even if the subject was considered "wrong" it would still be on the site -- albeit in the archive for a very small number (<15) specific articles which were found to either be defamatory or broke editorial policy on misleading content.
