Praise be to Allaah.
There is no problem with this because it is a way of organizing things in order to reach the right or better opinion, by using points to represent groups according to their size or number of members. But you should know that a "one man one vote" system may be unfair if the people involved are not equal in trustworthiness, ability, knowledge and experience that are necessary for the kind of decision-making that you want to undertake. If they are equal or close enough, then "one man one vote" is fair and wise. The people of authority (ahl al-hall wa’l-’aqd) in this ummah are those who have knowledge and virtue, who are rational and wise, and who are prominent and distinguished. These, not the ignorant masses whose opinion is worthless, are the ones who select the khaleefah. May Allaah help you to do that which will please Him.
