We’re talking about an entire complex network of political and business elites who have been granted access to power, influence and wealth by the Bidens, from the Delaware-based financial companies, to the Zionist lobbyists, to the military industrial complexes who benefited from Biden’s championing of the Iraq War.
Joe Biden is old and senile, but if he goes down the pillars that have been delicately supporting the entire structure of the elite network would be in jeopardy, not to mention internal strife and power vacuum within the Democratic Party.
It is too late for another primary now (which is when all this bargaining for political favors with the candidates took place), and there is no way to swap him out because people have already paid the campaign (through campaign fundraising) expecting favors in return of their investments, and they do not want to see all that go down in drain. Everyone’s in the same boat and do or die together.
Rather lose to Trump than to let Bernie win. Biden got lucky with Covid though.
