So here's what just happened: they announced the final vote tally which included 4 votes for Mitt Romney and 5 votes for Ron Paul (Paul had more than that but not every state said who the other votes were for).
So then someone motions to make the vote for McCain unanimous. "All in favor say Aye ... all opposed say No"
Some were opposed.
The motion passes.
So how can you use a simple majority process to change the vote to make it unanimous? How can you even propose that at all?
