Not just a senile idiot, a creepy-as-fuck, possible pedo senile idiot. We've seen this incredibly bizarre and disturbing footage of Biden, but most normies haven't. The President just put it on blast to the whole world.

Plus, Obama being shown as embarrassed by Biden is brilliant. Because it captures something obviously true. Obama waited a weirdly long time to endorse the guy he previously selected as his Vice President. In fact, he waited until he essentially had no other choice. And his endorsement was pretty tepid. Why? Probably because Obama knows that Biden is senile and creepy as fuck, and that his campaign will be a disaster. This is highlighting that fact in a very funny and effective way.
