Joe Biden must watch Sanders fight this way and regret that he did not make his own run at Clinton, and raise this kind of hell. There had to be a part of Biden, a father forced to mourn the passing of another child — his son Beau this time — who perhaps thought he was too old to make a run. But Bernie is a year older than Joe Biden, born three months before Pearl Harbor. He will turn 75 in September. Somehow he still keeps coming. At a time when Trump keeps talking about walls that will never be built Bernie, by God, keeps acting as if he wants to tear them all down.
