Well, there's the issue of TRMP as a symptom of flagging Democracy, democratic/republican values, and character issues in general.
There is an issue as large as any over the impact of the internet.
There are major consequences on actions of the LEFT as well as the RIGHT.

Getting back to TRMP I feel there has been a lowering of the bar of quality for behaviour on all fronts. He has, IMHO, a marvelous ability to corrupt, and then justify corruption not only for himself but for others whether in support or opposition.
