I think that Biden will win Iowa, but that will be the end of the Chism Trail for him. Harris will win California and will be crowned ala Hillary. She will be a tough candidate but with flaws at least as large as Hillary.
I said it a while back when this all got started, I think it’s going to be Harris. Simply put, because she’s ‘black’ and female. The Dems are all about identity politics, and it’s going to be the old “if you don’t vote for Kamala, then you hate women and you hate blacks”. It’s as simple as that. And the woman is cutthroat and Machiavellian.
