LOS ANGELES (KABC) -- Voters encountered some issues at early voting centers in Los Angeles County Saturday as several Democratic presidential candidates prepared for visits to California, which is the biggest prize on Super Tuesday.
The county added hundreds of early voting centers over the weekend, including at the Hollywood Bowl where some voters were met with confusion. Multiple voters said the center was closed when they tried to cast their ballot Saturday afternoon.
Meanwhile, some were concerned over the electronic voting system. However, one man at the Hollywood Bowl voting center on Sunday morning said he experienced a seamless process.
"I think it could be a little daunting, a little scary for the older generation," voter Steven Campbell said. "But I think once you're actually standing in front of it, it's just a big screen and you're just tapping things, it's really easy. I think anybody could figure it out, especially with a little guidance."

Officials still suggest voters plan ahead to give enough time for lines and the new electronic voting system.
Meanwhile, Bernie Sanders is scheduled to hold a rally at 5 p.m. Sunday at the Los Angeles Convention Center while two of his Democratic presidential nomination opponents also plan to be in the region before Tuesday's California primary.
