That is true, but we don't need Trump for that.
Nope, society has been moving that way for a while, Trump (and Hillary) is just another symptom. It was on full display for the Hope and Change election.
Even with Bush V Gore, both sides hated the other side, but from just a candidate on paper perspective, you had a highly successful governor versus a sitting Vice President so the resumes for the job at least reflected what one would expect.
Now, we've gotten to the point where it is a carnival barker versus a no results coat tail rider. You have the two least qualified candidates out of their respective fields. One winning his primary due to catch phrases and the other, due to her gender and name.
