Voting doesn’t work when the candidate needs campaign money to get voted for.
If the candidate needs campaign money to get voted in, then the candidate will automatically be corrupt,
as no one is going to freely give someone lots of money unless they expect something back from it,
and if candidates need to be on tv and pay good money for being on tv,
then the candidates choices are to be corrupt or to be unknown
and you will need to organize a different system of electing leaders.
