Booker drops out. One less of the "killer B's" in the race (Bernie, Biden, Buttigieg, 'Buchar...). I'm torn between Buchar and Bernie, at this point, so I can see them together on the ticket. I could see either as top of the ticket, but I think Bernie due to his age has only one shot at potus and one good term if his ticker holds out. So age before beauty.
