Are there a lot fewer polling stations in the States than there are here in England? Where I live we had a turnout of 64% last time, and no queuing at all so far as I could see. I know you have a much more complicated set of votes than we ever do, but that would just need a few more voting booths than the two we've got in our local school. The number of potential voters doesn't increase even if it takes longer for each one to vote.
