You are very wrong about that. They were showing up to the County conventions and getting their names on the ballot. HOWEVER, there are enough Cruz supporters who are Party stalwarts that they won’t be needed. This isn’t like it was with Ron Paul when his supporters were all newbies. It’s going to be a very interesting election on Saturday.
I’m in northern AZ and a Trump supporter but not a delegate. What possible good can I do at this point by going to the convention on Saturday if it’s too late to become a delegate?
