text:  Joe Biden's border because he has strength and substance. I think, look, every American would agree we have to have a strong president. The real question for this election is how are we going to define that strength? Is it in substance where Joe Biden has a kind heart, inner strength, the right values and has been doing this ably for a long time? Or are we going to look for strength in style, which comes through contempt and flair and sarcasm and kind of things that the Trump brand has tried to present?
