A private commissioned chaired by President Carter and Secretary Baker has proposed election reform that is so common sensical that I'm sure it won't become national policy. From the NYTimes article:

These are the main recommendations:

¶States, not local jurisdictions, should be in charge of voter registration, and state registration lists should be interconnected so voters could be purged automatically from the rolls in one state when they registered in another.

¶Voters should be required to present photo ID cards at the polls, and states should provide free cards to voters without driver's licenses.

¶States should make registration and voting more convenient with innovations like mobile registration vans and voting by mail and on the Internet.

¶Electronic voting machines should make paper copies for auditing.

¶In presidential election years, after the Iowa caucuses and New Hampshire primaries, the other states should hold regional primaries and caucuses at monthly intervals in March, April, May and June, with the order rotated.
