I lived for 15 years in Nevada. Which had “None of the Above” as a choice on every state ballot office. It was a nice gesture, and occasionally NotA got the plurality.
If NotA did win the plurality the result was to discard those votes and declare the second place runner-up the actual winner.
If we had a system more like Australia’s where you prioritize your votes from most to least favored, AND we added in a NotA option, that could be a powerful way for folks to register their displeasure in a way the parties could see, while still letting the people retain influence.
An interesting variation would be to have secondary and tertiary votes count for some declining fraction of a whole vote. e.g. if your first choice wins, your vote counts for 1 vote. If he/she is instead eliminated, your second choice vote counts for 90% of 1 vote. etc.
Alas, we’ll never see any of this fancy stuff in the ignorant and tradition-bound US of A.
