It’s of course entirely premature to speculate on the 2020 Democratic vice presidential candidate. Vice presidential selection depends heavily on which presidential candidate makes the choice, the options available, and the political context in June or July of a presidential election year when the decision is made. The selection is relational as well as contextual; each selector has different perceived needs, values, and judgment, and those factors shape the choices made. We won’t know for some months who will choose from what pool and in what circumstances.
That obstacle hasn’t stopped others from launching the names of prospective running mates into cyberspace, however, so it may be useful to recall some historical generalizations regarding vice presidential selection (in addition to those suggested above). CONT.
