Why State Delegations Vote Together
Each state delegation designates someone who holds up signs indicating whether delegates should shout "aye" or "no" at the opportune moment. Also, a green "yes" or red "no" sign can specify whether the opinion is that of the state affiliate's leadership or its caucus. There's also a "your choice" sign.
Delegates aren't bound by these indicators, one of the sign-holders explained to me, but it helps explain why so many votes go down according to state lines.
