California voters faced a tough time at the polls [on June 7th], with many voters saying they have encountered broken machines, polling sites that opened late and incomplete voter rolls, particularly in Los Angeles County. Many California voters were handed the dreaded pink provisional ballot - which takes longer to fill out, longer for election officials to verify and which tends to leave voters wondering whether their votes will be counted. It's difficult to get a sense for how widespread the problems are. Tuesday's voting problems seems to be a confluence of factors - old voting machines, a competitive election that has drawn new voters, plus complex state voting laws that can be hard for poll volunteers and voters to follow. Albert Grey showed up at his polling site Tuesday morning to find that the vote-counting machine seemed to be jammed, and there didn't seem to be a supervisor on site. So he left without voting. Many California voters reported showing up to their polling sites only to find that their names were not listed on the voting rolls, leaving them to cast a provisional ballot. Sanders supporter Jonathan Daniel Brown accused Democrats of purging votes" when he discovered he was not on the voting rolls at his polling station despite being registered. Brown ... refused to take a provisional ballot, and his complaints drew the attention of Los Angeles County Registrar-County Clerk Dean Logan, who intervened. Eventually, Brown said he was allowed to cast a regular ballot - though not before Brown said a poll worker called the police on him.
