Trump sure is the exception to that rule!
Being rehearsed is not being glib. Being glib means not putting any thought into the answers. Do you think that Trump gives ready answers without having thought about the question over the years?
Liberals are glib, because they can create matter, like on Star Trek. It will be easy to produce a train car for every individual in America. They ask questions like, where are we going to get all this copper, because the copper will just be there. Where are we going to get all this steel for track, no problem because we will just find the steel. Where are we going to get all the aluminum for the train cars? We will have it. That’s glib.
Trump has done the cursory research for his positions. He doesn’t do glib, even if he does rattle off the information in a superficial way.
That’s the best way I can explain it. If somebody can’t see the difference between rehearsed and glib, I don’t know how else to explain it. Glib answers are unresearched answers, I guess is a good way to put it.
