You're exactly right. They were all on a first name basis, even with their children which they brought. It was like the twilight zone.
When we went to vote for delegates, they wrote each delegates first name and last initial on the board and we stood in front of our name. A woman wearing a Romney shirt knew all the names of the Romney delegates without even asking, even though most of the Romney people there seemed a little unclear on what they needed to do to run as a delegate.
