Vote for yourself.
I don't think I'd want the job.
I suppose. But spoiled ballots are also caused by people who can't following instructions.
We should be able to vote for none of the above. If none of the above wins, then the election has to run again with different people.
The flaw in that system is that it could lead to an endless series of revotes. For that reason alone I'd oppose that solution.
In principle, I think a name ought to be chosen. One solution would be to include a blank space on each ballot where you can write in the name of whomever you think ought to win. As long as that person is clearly identifiable (put in his e-mail address, phone number, or some other unique identifier), then that vote ought to count in principle.
Of course even is we did that it would be almost guaranteed that the winner would be a person whose name was already on the ballot, as that's how most people would vote.
In principle though, should the unlikely event occur that someone whose name was not on the ballot did in fact win, then we'd have to treat it along the same lines as jury duty, whereby the person would have to actively decline the offer with good reason if he doesn't want it.
In the unlikely event that some person did win that way, well then you'd know you've found gold, a person the people could truly trust, who could win a plurality without his name ever having been printed on the ballot, with the people themselves having chosen him. How much more democratic could you get than to add a blank space on the ballot for the citizen of your choice.
