Whenever personal power becomes a main focus it sows division and corruption.  Which is one reason Jesus made clear on various occasions that he was calling his disciples to servant-leadership--even before he washed the apostles' feet at the Last Supper--to put the will of God and the common good first and self-interest and personal power last.   
We do know of some who truly heard this in their hearts--Pope John XXIII comes to mind-(and even in the secular world--A. Lincoln).  Most leaders struggle with the conflicting demands made on them and  muddle through. 
Some things cannot be decided by democratic vote--the force of gravity for example.  
And consulting the faithful IS good.
The question is--how do we get people to put God and the common good first?
