Adding "none of the above" to every race is one of my favorite fantasy ballot reforms. If no candidate wins, the contest is a do-over, with a new slate of candidates.

The second benefit, for election integrity activists, is preventing the "under vote", where down ballot races which are left blank, and potentially filled in by helpful administrators.

Note that in the US, ballots in metro areas can easily have dozens of races. Sheriff, judges, schools, water district, city, county, state, national, referendums, levies, etc.
