 They are putting their heads down and pushing forward. I asked a campaign directly, a campaign official directly whether Biden should step aside. And his response was absolutely not. The Biden campaign has always acknowledged that Joe Biden is old, sometimes more defensively than others. He's 81 years old. Every day he gets older. That is something they can't change. And yes, they say Biden did not have a great debate performance, but that doesn't change who he is and it doesn't change who his opponent is. That's the message they're settling on.
