Joe Biden is a 'Real Joe." He always has been. His advocacy for the Middle Class has nothing to do with politics or strategic positions, it is real. Very real. Joe is more of a 'Real Joe' than any phony GOP facsimile.
The Vice President was not stylistic during this debate. That was Joe. That was the man. He is attached to his life emotionally in a very healthy way.
If the Vice President was astonished by what he heard, then he was astonished. If he was smiling it was a non threatening way of him expressing his amusement (smiles) with lies and/or misguided ideas (rhetoric) then he was absolutely amused by the deception he was hearing.
Simple. Joe is Joe. There is no style choice here except the color of his tie.
