Please no! Keep it a simple straight up counted delegate vote on the 1st round. This is critical. 1st round the pledged delegates are pledged to the choice of the voters.
If they had a voice acclimation, some troublemaker would claim it was not unanimous. The next claim would be that that constituted the 1st round of voting and now delegates are unbound. Next thing you know we end up with Jeb.
okay. scratch that idea. cancel. cancel.
