I think Kevin de León should be considered to succeed Mr. Bauman. He has skills and knowledge the party would benefit from. He should make an effort to patch things up with Dianne Feinstein.
No political persuasion or type of person is immune from the human phenomenon of abusing power. Sexual harassment is one form of abuse of power. Verbal abuse is another. Anyone in a position of power is at risk of abusing that power. This is an important point that many people in a position of power forget or perhaps were never consciously aware of. Having policies for appropriate conduct —and enforcing those policies—is an important means of combating this phenomenon. (Power corrupts; absolute power corrupts absolutely.)
