Washington (CNN) Vermont Sen. Bernie Sanders said Wednesday that it "is a disgrace" that some Arizona voters waited in line for five hours to vote because of too few polling stations. "In the United States of America, democracy is the foundation of our way of life," the Democratic presidential hopeful said. "And what happened in Arizona is a disgrace. I hope that every state in this country learns from that and learns how to put together a proper election where people can come in and vote in a timely manner and go back to work." Sanders said during a news conference a supporter emailed his campaign complaining about the long waits.Some Arizona lawmakers and activists are accusing local officials of voter suppression tacticsThe Arizona Democratic Party has asked voters who had a difficult time voting to complete a form online explaining their challenges
