The election of t-rump is a wake-up call. One can legitimately say that it represents the  value priorities of at least one-third - and a powerful third - of USA voters and the "voted". The continued tolerance, especially by leadership, clearly demonstrates an operative value system that is not only at odds with self-attributed national values but human values; that will blatantly lie, manipulate, dissemble and intimidate. It is not just that "politics is dirty" but rather the degree to which it is so.
Suitability to govern is not solely a legal/criminal matter. It is a standard of judgment by intelligent people of good will who are responsible for the common good of all citizens, your code of values and not only a code of law.
