So far, based on Biden’s choices, three trends are clear.

1. Both the Black establishment and the Latino establishment within the Democratic Party have real clout, able to essentially force Biden to pick some Black and Latino appointees for key posts and to block some people they don’t want.
2. The progressive wing of the party doesn’t seem to have enough clout to get its people key jobs, but does have enough power to prevent Biden from picking people they strenuously oppose.
