There are a few things that could be done to improve the electoral process in USA.

An easy one would be to have people vote on weekends instead of Tuesday.

The second would be to have more polling station so that people don't have to wait hours to be able to vote (alas this seems to be by design).

Since we are there, but unrelated to the amount of people voting, fix the vote counting process so that you can get the result the following day.

The stuff above is not rocket science and is what most of the other civilized countries do.

If people still don't go out and vote, probably is because both candidates suck, or they don't look so much different one from the other. Fixing this would require changing the electoral system, which is not something I see done anytime soon in the USA

Also on the list: Tackling the electoral college thing such that every voter contributed equally, regardless of their home state.

I don’t live in the US, but US elections have quite an influence and it’s frustrating to see a system I perceive as very flawed having such an effect here, at the other end of the world in New Zealand.
