Surely there’s one better young person in the USA ?
None of them ran. Biden’s admin and his fund raising base held enormous sway over the party at-large. As soon as he corralled the support of this tiny monied elite, everyone else had to either get in line or get marked as party pariahs and ousted for their disloyalty.
The pastiche of democracy is predicated on a primary system that can produce and sustain rival candidates. But when leadership in the party are terrified of “Russian bots” and “Leftist Antifa Agitators” undermining the general election, they circle the wagons around their incumbents and bow down to their mega-donors out of cowardice.
No rival candidates means no real primary means no one actually challenges Biden on his merits.
