Another example of that is how they have done the speaker arrangements. Many have noted how each night they seem to put the headliner at the beginning of the primetime hour and not finish big, leaving half the audience leaving while Joni Ernst is talking for example. CNN reported yesterday that again old RNC hands wanted to do it the usual way (end the night with the big speech) but the Trump people rejected that.
I think Trump is right on getting the most important headliner at the beginning of the primetime hour. The 10PM hour, when the broadcast networks join the coverage, is the least-rated of primetime because many people go to bed. Putting your most important speakers later runs the risk of having a smaller audience, especially if the networks go with boring talking heads instead of showing the previous speakers, or the previous speakers bomb. It also runs the risk of running late and having the networks cut away from your speech if it's too boring. Putting your most important speakers earlier ensures a greater audience, at least on the East Coast. And, as Muon has been telling us, it runs the risk of the main speaker speaking to an empty floor, as delegates leave for parties and get togethers.
