With Joe Biden’s formal announcement we have 20 individuals who want to be our party’s nominee for President in 2020. (See the list here.) This group is definitely the most diverse and well-rounded group from which we get to chose. We should be heartened that so many talented people have decided to step forward and put themselves in the running.
Diversity comes in many ways this time: by gender, by philosophy, by age, by background, by orientation. This group has it all. One would believe that anyone should be able to select a favorite from these 20. And who knows, there may be more.
So start going to the websites linked. Read up on each person regardless of whether you think you know them very well or not. You may be surprised at what you find.
