The image the Republicans have of themselves needs the image they have of the Democrats to bring it into sharp focus. The Democrats are plainly a disreputable crowd; the Republicans, by contrast, are men of standing and sobriety. Many a middle-class American in many a small town has had to explain painfully why he chose to be a Democrat. No middle-class American need feel uneasy as a Republican. Even when he is a minority--for example, among the heathen on a college campus--he can, like any white, Anglo-Saxon Protestant, warm himself before his little fire of self-esteem.
