I think that is the overwhelming part of the calculus and it's a great idea. The more people see Trump the less they like him.I assume a large part of the calculus here is the idea that the more regular people hear and see Trump again the less they'll like him instead of effectively imagining him as kind of a vessel for their own views again.
I also think the average American has not seen Trump speak recently or at least not at any length. He is constantly slurring words, saying outright gibberish, or losing his train of thought and sort of trailing off into nonsense. He seems very unwell.
