It had better be the Trump convention. If his people aren't controlling, then it's time to quit and go home. The history of these things has shown that the candidate who is in position to be nominated, should be controlling every aspect of what you see and hear. The platform, the speakers, the deals, etc. Democrats and Republicans have been masters of this for six or seven decades. If LBJ had let RFK speak before the nominating roll call in 1964, he would not have been nominated, as was evidenced by the 15 minute ovation and demonstration that Kennedy got. It was all in the scheduling.
