It is refreshing to have a modern candidate for President. Senator Sanders will not be preaching about sin and the moral decay in his campaign. Republicans will talk about that.
I’ve read that Sanders has a special dislike of Bible thumping politicians. I hope he lets people know how he feels about them. Perhaps a goodly portion of the public dislikes them as much as Sanders does.
I would expect Sanders to not only express openly he is not for inserting religion into politics but to also contrast himself from Republicans by being a Big Picture candidate. While Republicans will discuss petty issues like gay marriage and abortion, Sanders will discuss the growing income disparity and participation in wars around the world.
We know conventional wisdom is that Sanders cannot win the Democratic nomination. There is just now a feeling of uncertainty about current politics. Republicans seem determined to move further and further to the right. Perhaps Democrats are moving further to the left more than most think possible.
This period reminds me of politics during the Vietnam War. When it started there was a general consensus it we should be over there. As time dragged on, the majority began it see it as folly. That the establishment in both parties supported slogging on in Viet Nam gave rise to the candidacy of liberals George McGovern and Eugene McCarthy.
Sanders is a non practicing Jew. It will be entertaining to see his answer to the question, “Did Jesus ask you to run?”
