If you were to redesign the election process in the U.S., what would it look like?

Assuming that we have some common goals in mind (reduce voter fraud & suppression, maximize participation, etc), what would be the best way to accomplish this?

- Would you support an online voting system?
– Would you support a federal holiday to allow people to vote?
– Should we be using paper, electronic, or a combination of both types of ballots?
– Should there be a way to confirm that your vote was counted?
– Would things be different for primary vs general elections?
– Should we do away with caucuses?
– Should there be a federal standard for all election rules and processes, so that states are not allowed to make up their own?

And what about voter eligibility and registration? Should this happen automatically at 18 years old, or should there be a manual process for registering? Should there be any actions which a citizen could take that would invalidate their right to vote (felony, etc)?
