Kamala had to drop out per the rules because she wasnt polling high enough. Her own group didnt want her.

But the party was smart about it. They figured out a way to tie together both sides of the Democratic party: the really old school democrats would be happy with Biden who is as old school as you could have. The radical leftist who wanted someone like Bernie, would at least accept the person, whom has been stated as the most leftist senator in history, and a "POC" either black or asian depending on whatever contex. Together the party did not alienate anyone, the old school dems, the radical leftists, and the race antagonists
