When I see that the US uses voting machines and takes ages to count votes, my instinct is to support a reform of "just do it like Australia/the UK/other civilized countries", where:
- all ballots are paper
- there's no such thing as provisional ballots
- postal votes have to arrive by end of voting election night
- on election night, ~all votes are counted by hand, observed by scrutineers employed by the candidates
One issue is that this is maybe somewhat of a simplified account of how places count votes (aec.gov.au/voting/counting/). But I also wonder if it's just one of those things the US could not implement if it tried, due to lack of the relevant kind of "state capacity".
