Recently Orson Scott Card wrote "Empire" A Tor Book - Published by Tom Doherty Associates, LLC 2006.
It's not a great read.
it's not bad, but not as good as his Ender's saga.
At the end of this book there is an essay.
The essay at the back of this book is really good.
It takes a look at the American political system and the dangers hidden there within.
I highly recommend that you read this essay before you vote in any more elections.
