All true. The issue here, however, is not Biden's amazing past, but his ability for the future. He keeps failing in persuading he is still in a good shape even those who value him, while to win he has to persuade those who are on the fence. I'm really very sorry, I think his achievements are amazing, but they are the part of a glorious past. Here and now we need someone who can win. The alternative is a threat, much more to the world than to the US.
