This is the classic “trial balloon” to guage public reaction to a possible candidate.
May I suggest a possible slogan for the new “team”: “Keep Kaining them until morale improves!”
Ordinarily I would agree. And you still might be right. But time is getting short for Hillary to make a pick before the convention (next week). If she doesn’t pull the trigger, the convention may hand her a running mate she doesn’t like or want.
