If the headlines this morning mean anything, Graham Platner is done – put a fork in him – the Democratic Party is abandoning him as fast and dramatically as possible.  Politico says its over.  The Atlantic calls for him to be “cut loose.”  The NYTimes says he has been “abandoned.”  That’s a liberal trifecta if ever I saw one.  Conservative forces agree – the Platner effort is at an end. That which was once astonishingly ascendant is now at the bottom of the slide headed to the dumpster.  Man, did that happen fast.  What lessons can we learn from this?
