I do not know if it was a defining moment but I thought the speech was his best one so far. I think it had to do with the huge crowd which buoyed him up and made his leadership persona shine. He was definitely in great form and the script was very substantive.
Yes, it was a great speech and wonderful crowd! I was really amazed how well the entire event was ran. No problems getting into or out of the Convention Center. Great Job Greenville!
