Who can vote than?
Is this some closed circle of moderators, admins and managers in forum?
If you guys want to make forum really more decentralized than voting should include more members, starting with higher ranked active members.
In reality, that's right, it is a "small" closed circle (moderators, judges, administrator and some more), which from the beginning of the forum decides by vote who would be president and vice president.
Your suggestion (you can write a thread about it in the corresponding subforum if you want) I don't know to what extent it could be carried out. As you know since the arrival of the mixers, and many users, the forum has seen quite a few changes, listening to suggestions from users, but I don't know if the administrator would be willing to open voting. But logically I could be wrong.
