two old white guys, that's why. it has nothing to do with policies or platforms. if you haven't noticed, identity politics are front and center in this election.
biden has already vowed to pick a woman VP, so technically that's why it's impossible. in terms of odds, it's pretty clear by now that it will be a non-white woman. i'll be very surprised if it's anyone besides kamala harris or susan rice.
Not just the race, but also it's about the age. Biden is a few weeks away from 78. Bernie is almost 79. Do you really want a 78-year old presidential candidate, with a 79-year old VP pick? IMO, race is secondary concern. And age is one of the advantages Kamala Harris is having, as she's just 55 years old. But from what I have heard, some of the top Biden allies and donors are not happy with her, and want to prevent her being named as the VP candidate at any cost. It looks to me that Biden can't ignore their stand. In the end, he may come up with another compromise candidate. May be African American and female, but not Kamala Harris.
I heard that other candidates for VP are: - Keisha Lance Bottoms, mayor of Atlanta,
- Keisha Lance Bottoms, voting rights activist
- Susan Rice, Ambassador to the United Nations, and National Security Adviser etc.
Personally, it seems to me that Susan Rice is the most qualified candidate for the position of VP and I hope that Biden will choose her.
When the whole world is in confusion and chaos due to the corona crisis, America-China relations and many other reasons, Biden needs someone experienced in foreign policy.
