The tension between ex-serviceman Dale Barbara (aka ‘Barbie’) and Rennie is uncomfortable. As the outsider, Barbara is resigned to accept his low social status in the small town of Chester’s Mill. While the character’s past life includes being a decorated war veteran and intelligence official, he finds himself inside the town border as a short order cook and the target of suspicion, aggression, and scapegoating. Like many immigrants within our borders, his past life and achievements are invisible. At the halfway point of the book, at least, he is the quintessential "suspicious foreigner" who plays a critical servant’s role in the small town, while being despised by both the town leaders and its privileged sons.
Rennie is a monster on par with any King has unleashed. The small town political figurehead is outwardly a born-again Christian, with the dangerous self-assurance that he is always right. A used car salesman and second selectman, Big Jim brings out a voice in our culture which is everywhere in our political and cultural headlines: "I’m right, but you’re stupid and going to Hell." He is most dangerous behind the scenes, passively but aggressively manipulating the town, its officials, and its resources to personal gain.
Most intriguing is King’s attention given to the spiritual condition of his characters in Under the Dome. In King’s 1974 book ‘Carrie,’ title character Carrie White has a terrifying mother whose religious zeal, suspicion of the world, and abusive nature combine to show the dichotomy between a public faith and a private failure. 36 years later, the townspeople of Chester’s Mill who express any public faith carry their own shortcomings. From substance addiction to abusiveness, each Christian character is either struggling or is completely ineffective in a moral sense. Mostly, the town would be better off without them.
With the second half of the story still unknown, it’s difficult to guess where the story will turn. But that’s true in reality, not just in fiction. As we find many in our nation quick to demonize, stereotype, and label people who are different than "we" are, it really is hard to tell where the current tone will lead us as a nation. If it’s anything like a real Stephen King novel, the end could be pretty scary indeed.
