At least one woman with a bullhorn confronted and yelled at voters arriving at an early voting site in West Palm Beach last week. Sheriff's deputies asked the woman to move – but not before some voters left without casting their ballots.

In at least nine counties in Texas, polling sites posted outdated voter ID requirements that had been declared unconstitutional.

In Georgia, voters waited in line for as long as five hours in Gwinnett County, where close to half the residents are black or Latino and only one voting site was in operation for more than 400,000 eligible voters.
