So what will happen at the convention is, Priebus will step up to the mike and announce "The proposal put forth is to keep rule 40! All those in favor?"
[THUNDEROUS SHOUTS OF "AYE!"]
"All those opposed?"
[crickets]
Priebus slams the gavel. "The 'Nays' have it! The proposal to keep Rule 40 is turned down; Rule 40 is removed!"
The delegates can make it by recorded vote.
