Are Trump voters even listening to their leader, or is it just the rest of the world that has to suffer hearing his logorrhea?

I do not know, never having been one. I can only say that it doesn't seem like they really do, many times. Other times, they find a way to somehow defend just about anything he utters or writes/types.

In the meantime...I love learning a new word, and this one is surely fitting for him.
