Watch Biden's expressions as Ryan is speaking. He rotates from laughing to smirks to surprise to smiles. He's like a clown.
In the first 15 minutes, my take is this... Ryan look crisp, lucid, young and in control. Biden looks like a babbling freak who they just wheeled out of some retirement home after they just revived from a code blue.
He is not like a clown. He is an actual clown in every sense of the word. It is frightening that Obama would select such a character to serve in a capacity that could elevate to the Presidency should something unforeseen occur.
