Thomas Frank's book _What's the Matter with Kansas_[0] explores this pretty well. Some of what he proposes is a bit over-simplified (ie that all conservatives prefer to vote for morals over pragmatism[1]), but his main thesis -- that the conservative platform has created a moral argument convincing poorer Americans to vote against the very social programs that they rely on -- is a good starting point for considering this.

Personal note: I grew up rural California; Frank's thesis describes the adamant, self-defeating narratives that I regularly heard from my neighbors.
