I disagree with your analysis. I think you greatly underestimate the number of voters in North Carolina who do not register as either a Democrat or a Republican. I'm not suggesting ignoring those registered as independents. I'm suggesting going after registered Republicans is nothing but fool's gold. The only way that registered Republicans are going to be changed is some variation of the old saying, "Experience is a harsh teacher, but a fool will learn no other way." Or some variation of a line from Dicken's "Oliver Twist," that states in regard to husbands being legally responsible for their wives because wives do what their husband instruct them to do, IIRC, "If the law supposes that, the law is an ass--an idiot. If that's the eye of the law, the law is a bachelor; and the worst I wish the law is, that his eye may be opened by experience - by experience." But even I am not harsh enough in my regard for rank-and-file Republicans that I wish their eyes should "be opened by experience."
