At a time when Democratic leaders from Richmond to Washington and beyond are inarticulate, cowed and flustered, we have Vermont independent Senator Bernie Sanders. After seeing this performance, I may have to reassess my opinion of him. Until last night when I saw him on “The Last Word,” I thought he too often sounds a little too angry. He still looks angry, which would hurt him as a spokesman, but his passionate and clear speaking was a breath of fresh air. My daughter commented on his cogency while we we watched him.
