Biden was in the Senate for decades. Long before computerized records of everything and cell phone cameras were everywhere His idea of playing dirty is exposing his fellow politicians private lives. I guarantee even if he led a boring sex life, he knows all the details of the powerful who didn't.
He protected pedophiles? Then he's no better than Donny.
i’m sure he has his own secrets too. Not in the same vein, but stuff that he didn’t want getting out with family or friends he's made in politics. He is more loyal to those relationships. But R side doesn't respect that way anymore, and the D side... Well, the new blood knows what's up at least.
