After eight months of funerals, for hundreds of thousands of American families, the kind of grief that Biden speaks of, the kind that accompanies the loss of a loved one, is no longer distant. The president stood in front of that grieving nation, and taunted a father while he was speaking of his lost son. Before the eyes of a nation struggling with an opioid epidemic, he mocked a dad for having a kid with a drug problem.
