The presidential post-mortems over the last three-plus weeks have been at once amusing and revelatory. The amusement comes from how much has been revealed about Democrats and their alt-left brethren (if there’s an alt-right, then there has to be an alt-left, although no one has referred to them as that just yet; think Bernie Sanders, Jill Stein, Black Lives Matter and the Occupy Movement). As it turns out, liberals and Democrats are just as churlish and childish as are Republicans and conservatives when they don’t get their way.
