Single voting a pest or genetics?

In the Philippines voting is an exercise of freedom but extremes can happen. Allow me to picture a situational in my article as follows.
Candidates come to an agreement forging a compact to include the entire line up or group among voting friends, clans, tribes and relatives. Then comes Election Day when secret ballots are cast followed by the canvassing and counting of votes and the winners are……. Of course the wily foxes!
Where did things go wrong? It is a common practice among clans and closely knitted groups like a tribe and similar groupings to vote for one candidate and excluding the rest of the group. The other candidates who unwittingly did a fair job of including all their team mates will get the least votes because they were never included by the others in the first place.
They say all is fair in love, war and politics but in this case integrity is the basic character that should be taken into consideration as foremost. A candidate who takes advantage of a situation appropriating opportunities to take undue advantage over others who follow the rules of fair play should never be in public leadership positions, because they will apply their wily and corrupt principles in all endeavors they do.
Among the clans and group who follow this kind of unfair practice find themselves fooled most of the time by the same candidate who approach them in every election wearing different masks. These same clans, tribes or groups seemingly never learn. Their ability to distinguish wolves in sheep’s skin has never been sharpened. It seems to be a hereditary aberration and it is now already a genetic adaptations.
