Biden was brought in as VP as he knew exactly which Senators could be flipped, turned, bribed or infiltrated.
One of the reasons the GOP-e Senate has been so pointless.
Of course it has been pointless for decades.
Bidens never been a real bright bulb....he hides behind his dumb humor as a distraction. But Obama and Biden were selected to NOT shake the boat and would be rewarded with a untarnished ride into the sunset with their pockets full after their terms.... Just as we see the Obamas enjoying today who continue to bring in the dough.
