Books to teach during 2012 election

I was trying to think of ways to teach about the upcoming election next fall in 10th-grade English. And while I've got some ideas about lessons/projects where students can analyze media messages (in TV broadcasts and commercials), practice research skills (about the issues and positions of candidates), and discuss controversial issues (either about the election process or the issues themselves), I'm struggling when trying to find literature that connects to the many issues that are brought to the forefront by an election (how conflict is resolved in a democratic society, how competing ideals are balanced, what the responsibilities are of citizens, how campaigns try to convince voters, and on...)

However, I'm struggling to think of a work of literature (or excerpts from works of literature) to read during this unit that would connect to some of the issues mentioned above. I also thought about reading of excerpts of memoirs about persons describing their process of political socialization...but what memoirs?

A third idea I'd had is to read and analyze excerpts from books by both Obama and Romney: Dreams from My Father and No Apologies...

What books/articles/plays/memoirs/writings do you think would be good to teach in 10th grade English class during the time leading up to the 2012 elections?

(An aside-- I ask this question with the belief that discussions that involve students' political belief are something that should be present in the classroom, a belief no doubt many posters in this previous thread would disagree with: http://www.awaytoteach.net/?q=node/2686&page=3 )
