Voting and proportional voting.
If you are a credentialed voter, you may vote for only one slate. You cannot transfer your votes to someone else to use. You must be present to cast your own votes.
Now for the tricky part. The counting. Proportional voting means that a slate with 3 candidates might only get enough votes for 0, 1, or 2 of their candidates to be on the Committee. You will want to think about this when creating your slate - as candidates, you need to prioritize and present in advance who would be elected to the Committee.
The number of seats a slate receives is determined by this equation: (Votes Received/Total Votes Cast) X Seats Available = Number of Seats Awarded.
If you have 3 seats and 20 voters in your group, that would be (Votes Received/20) X 3. If someone withheld a vote, then it would be (Votes Received/19) X 3.
