Voter turnout has always been a problem in American elections, particularly in off-Presidential cycle elections. It's bizarre, but at least in modern times we did still did use to hit 60% turnout on cycle and 50% off cycle as opposed to the trend today of ~50-55% on cycle and 35-40% off cycle.I'm not sure it would help so much in the USA because of the apathy here, but I think Germany holds elections on Sundays. They get much better turn-out.
Despite the number one given reason being "not enough time" - the real turning point? Vietnam, Nixon and Watergate. That triple whammy killed the electoral spirit.
I still think election days should be work holidays. I know employers are required to provide workers time to vote, but bah.
