People can’t be locked out, unless they simply show up way too late. Nobody knows who supports who unless attendees choose to wear buttons or hand out literature. Party regulars are never unified, and are used to accommodating each other.
But in my experience, Caucuses get to the point of having your loser candidate recognized as a loser, and throwing your support to the next best guy, and against the guy you hate most. I see that as Cruz-positive.
Thank you. The rumors are insane right now.

I think it was a joke...
