Steve Israel and Norm Ornstein correctly note that it would make a lot of sense to shift Election Day to a Saturday and then make special provision for the small number of observant Jews, Muslims, and Seventh-Day Adventists (with early voting increasingly popular and widespread, you wouldn’t need a big adjustments). This would be more convenient for most people and greatly enhance turnout.
You can see more on this at Why Tuesday? where, among other things, they make the point that the tradition of Tuesday voting is based on considerations that have absolutely nothing to do with modern conditions. Voting on Tuesday is, along with the electoral college and the filibuster, a dumb anachronism that we ought to do away with as quickly as possible.
