It is interesting to see how Bachelder attempts to walk the line between emotion and reason. In keeping with introduction to Passionate Politics, he does seem to recognize the importance of emotion in the way he develops characters. Sinclair, for example, evokes a great deal of pity, not only for constantly getting assassinated, but for constantly being torn apart by book reviewers, and having his quest for socialism repeatedly fail. By having us feel this pathetic old man is being wronged, Bachelder leads readers to think that his cause is being wronged, too--that socialism deserves more of a chance.
Bachelder seems to recognize the claims of Chapter 1 in the way he makes his book so openly humorous. He realizes that many people are not interested enough in social conditions to read a serious work of nonfiction or a blunt Upton Sinclair novel on the subject. Therefore, he writes a humorous book that many people would be willing to read whether or not they cared about the cause of socialism in the least. However, in the process of reading the book, and perhaps discussing it with friends, he may hope they will be influenced to support the socialist cause.
Bachelder's novel coincides with the message of Chapter 12 in more than one way. First, as Chapter 12 emphasizes how emotions are seen as more legitimate coming from men than from women, the main characters of U.S.! are all male. Sinclair in particular seems to be somewhat uncomfortable with women, especially with being intimate with them. Second, just as Chapter 12 discusses how overly emotional appeals are not taken seriously, U.S.! emphasizes how Sinclair's overly emotional novels, with their pitiable characters and excessive exclamation points, are laughed at by serious critics.
