IMHO it shows the enthusiasm gap if nothing else. These people will vote for Trump come hell or high water. However these crowds have been huge from day one.
Have u ever noticed that Trump is usually late to rallies, sometimes as much as an hr. Yet, the people never complain or protest. They remain polite to each other.
Then, when Trump comes down the ramp or into the arena: whoa, the crowd goes crazy. And Trump always claps. He is clapping for the people.
