Biden is, from where I sit, wrong on almost every issue, and his career is replete with examples of him stooping to political cheap shots and hackery. Unlike some other politicians, though, Biden also has risen to some occasions, has shown patriotism, and has legitimately thrown himself into his work in a way showing a basic consistency of overall principle even if full of numerous, mini-hypocrisies for short-term political advantage.
In addition to his unusually awful family tragedies, Biden also recovered, more than 30 years ago, from a terrible brain aneurysm that he was very lucky to survive. The man keeps bouncing back. He’s almost irrepressible.
None of this makes Biden a great choice for president. It does make him a man with real virtues amid his flaws.
