Thanks for catching that Kim. I should of said, As commander, you need only to vote to break a tie on motions before the floor. A commander should not make, second or debate motions as it is inappropriate. As I may have said before, an umpire is suppose to be neutral. He can not referee a game and be a player too. It would not be fair to the other team.
Every member has a right to exercise his vote. When a Commander casts his vote on motions verbally or by hand, those who are undecided may abstain or vote with you because of their faith in you or trust in you wisdom; or against you because if your for it - they want to be against it. That's the nature of some people. Simply, a Commander must strive be fair and try not to render undue influence while holding the gavel. Doing your best is all that matters.
Like IJK cheerily references, A good commander builds bridges - not walls.
