I really doubt the conclusion that most people would decide to negate, especially since the most outspoken gen negated fast, so a new person seeing that the people they hate have been negated, would instead cast a ballot for their preferred candidate. A lot of people would decide against a negation vote out of principle. And a many live in communities that are basically echo chambers and would not know many people they want to negate, especially since those people would keep their mouths shut.
Even if a lot of votes would be negated, democracy lovers would still claim that the 3 votes left for A outweigh the 1 vote left for B, so all hail president A.
