Well I must say that is not illuminating, especially considering there was no "landslide", unless maybe you were talking about the one that buried Sanders. Even that is debatable as a landslide, since the final popular vote count was Hillary55%  Sanders 41%. Sanders did well for a candidate without broad appeal. If there was any manipulation, it was by the popular media which ignored Sanders and even Clinton, in favor of their focus on the drama of the Trump campaign.  As far as actual voter fraud, there was none.  That is most likely what Bev Harris meant, that, in fact, you can't steal a landslide.  But there was no landslide. Your comment makes no sense.
