How I wish that it were so, but I have been involved in local politics. The people who get to go to the convention are the people who have been involved in the party the longest and have given the most. This is true all over the country. The party insiders all know this. In Tennessee, they not only wouldn't nominate Trump and Cruz people to be delegates, they wouldn't even let them attend the party meeting.
If no candidate gets a majority of pledged delegates before the convention the party bosses will pick the nominee and it will not be Cruz or Trump. We must start looking at what the actual outcome is likely to be. The time for animosity around here is now behind us. It is time we all start working together, or we will lose.
You speak truth. Cruz people are naive if they think the long term party insiders/donors who make up almost all the unbound and much of the bound delegates are going to nominate Cruz.
