[QUOTE=JetPotato;4255229]How do you determine that except for elections? So if an incumbent come up against his term limit and only gets 62% of the vote, does the runner up get the job? Would drastically change the candidate field that year too, no?[/QUOTE]
No - you determine it by the prior election. Say the term limit is 3 terms and you've served two, and are running for your third. If you get more than 65% of the vote, you can run for number 4 after term 3 expires (and so on, for each election you can garner 65%+ of the vote). If not, then your third term is your final term, and you can't run for number 4.
