From: Jd Lyall <postmaster@lyalls.net> White ballot is a normal term in election mechanics. "Blank ballot" would be how you would say it in common sense english.The former communist countries have a requirement that 50% of the eligible population must have cast a valid vote for an election to have force. Everyone who is eligible is on the governments rolls, so 'registration' to vote isn't a problem as in anarchy peyi'a like the usa and hayti.
Yugoslavia had this problem. People cast 'white ballots' to keep the election from being final. So, no one was elected a number of times.
according the cep logic, if blank would have won, it would have meant that the protestation against that election would be officialized by the majority and become irrelevant..
