The University of Chicago communists who figured out that you could use race to get Obama past Hillary Clinton's Superdelegate rigging of the Democrat primary system and then get fellow traveler Chuck Schumer to create a bank panic in order to promote Obama as a change candidate...had to sit back and let Hillary run in 2016 in order to re-unify the party.

Once Hillary lost, they implemented the next step, which to them was to tie Race to Gender and run Kamala Harris as their 2020 candidate. But Kamala Harris did so poorly in debates, they could not sell her. So they decided that Obama's DNC stooge Biden would have to be used to sell to the public.

They faked ballots and had their media insist 'this was the most honest election in history' and got away with claiming an unpopular joke cadidate Biden (who had never been better than 3rd within his own party's nomination for twenty years) was actually so beloved by blacks that he outperformed Obama.

He simply was the only 'credible' figure they had.

And that is the problem the Dems have going forward. White Boys like Gavin Newsome are not going to pull black voters (in an honest vote). Their party is balkanized they will have to try a Female or a homosexual as their next concept.
