I think Hillary underestimates the deplorables quite a bit. Those "deplorables" who seem to get all the press are the 30% of Republicans driven by gut reaction rather than reason. The red-neck, angry sign wavers, who populate Trumps gatherings, and who for the most part seldom if ever vote for anything. Employing reason is simply outside their innate ability. So calling them deplorable is like calling left handed people inept because they can't do things with their right hand like 90% of the population, and it really isn't fair. In reality, these aren't actually deplorables, but the all-too-sad lemmings who would follow Trump over the cliff. This leaves 70% of the Republicans, the truly deplorable Trump followers who, despite recognizing his demonstrated lack of character and ability to serve as President, champion him nonetheless. Of these there are two sorts. Those who want him in office because he will pander to their special interests---but unlike the 30% will stop short of going over the cliff. And those so committed to the Republican philosophy that no matter what kind of squirrel is put up for Presidential candidate they'll vote for it. They have no interest in sorting out the flaws of any Republican candidate, Trump included, and are content to ask, in effect, so what? Whatever the case, reason is lost on them all either because it's ineffective or dismissed out of hand.
