Hillary lost because she did not court the labor vote. She ran AS A WOMAN and, duh, didn't get as many men to vote for her as she needed. That's on her, not the misogyny of the American people.
Kamala Harris was an affirmative action hire. If Biden had run with a white man, or maybe even a white woman, he could have kept his promise to pass the torch. But Harris is unelectable. So Joe is still here.
The same message Democrat leaders are sending to Joe should be sent to Kamala: You cannot win the presidency. If he could see past his ego and she past her identitarian agenda, the party would nominate Gretchen Whitmer in a heartbeat, and she would carry the Blue Wall by not making Hillary's mistakes.
Being black didn't stop Obama, and being female won't stop a Democrat who deserves to be president. Kamala Harris just isn't that Democrat.
