BIG BOY BIDEN DID IT!!!!!
That was great in every aspect.

Addressing multiple demographics, races and age groups. Being pro union, talking about being middle class in a way that appealed to white voters which worked, stressing unity, being a empathic figure by sharing his grief to show why he understands people's grief. Having strength and conviction in his voice and strength as a leader by standing up to dictators. Could go on.
Many people seek the moment. This moment was seeking Joe. I'm convinced.
