Part is his eespext of people. Two stories
Last night before the sold out private event in Michigan he answered questions from press. He joked with them (spoke directly to Major apologizing for how O treated him) answered their questions sent them on their way early. They did not have to hang around and wait for a ceumb- - full accessibility
Recently in NH he rented a church parking lot and transport vans [parking was poor and at a distance) for his “guest” He also provided a tent for shade and water for the press
People respond not only to his message but to the respect he gives them.
Notice also how after he has made peace, he graciously acts like its no big deal and all is well. (Think Roger Ailes.) Trump is very smart by trying to bring adversaries into the fold. I won’t hold my breath on Rosie O’Donnel though. lol
