Quorum sensing is a very real thing, but your opening post anthropomorphizes it beyond recognition. Bacteria don't vote in the same way we do. They release chemicals that change gene expression in other bacteria, and often the most potent or most abundant factor will become the dominant quorum sensing signal.
It is a very automated system with no "thought processes". Due to the number of genes and species involved it is a complex system, but complexity does not mean intelligence. The weather is complex, but hardly intelligent.
