The Ethics of Voting will be out in two weeks, on April 4^th. [EDIT: Looks like copies are available now. Amazon has a temporary backorder, but Barnes and Noble has copies available now.] Over the next month, I will blog about voting. 

The introductory chapter is available here: http://press.princeton.edu/chapters/i9464.pdf

This isn't a book just for other philosophers, but for anyone interested in voting and democracy. As much as possible, I wrote the book in plain, simple language, and moved technical jargon to the side.*

Here are some of major positions I defend:

1. You normally don't have a duty to vote.
2. To exercise civic virtue, you don't need to participate in politics. 
3. Even though your individual vote makes no difference, when you do choose to vote, you have a duty to vote for what you justifiedly believe will best promote the common good.
4. Liberal individualists should not be skeptical of the idea of the "common good".
5. If you are not going to vote well, then you have a moral duty to abstain. You should not pollute democracy with bad votes.
6. It’s okay to buy, trade, and sell votes, provided you vote well. Buying and selling votes isn’t wrong in itself. It’s only wrong when it leads to bad voting.

I’m offering a special bonus for anyone who pre-orders the book.  Here are the rules.

1. Email me at ethicsofvoting@yahoo.com and tell me you pre-ordered the book.  ($24 hardcover on Amazon right now.) (Amazon, Barnes and Noble, Princeton University Press)
2. We’ll use the honor system—you don’t need to send me proof of purchase.
3. I’ll then email you a short, easy-to-read piece called “Responsible Voting”. This paper outlines and explains in simple terms why voters should vote for what they justifiedly believe will promote the common good. While the book goes in much more depth, this gives you a strong background in one of the book’s most controversial ideas.

Some reviews:

"Jason Brennan's surprising investigation of the ethics of voting grapples with some of the most entrenched dogmas in our political culture. His approach is open-minded, his writing crystal clear, and his argumentation of a high standard. His conclusions will shake some readers up, and our thinking about democracy will be better for the debates that are sure to ensue."–David Estlund, Brown University

"This is a fascinating book about a very important topic. Indeed, it is difficult to think of a topic more significant in democratic theory–and it is surprising that, until now, it has been so neglected. The Ethics of Voting abounds in interesting claims and good arguments with often surprising conclusions. Beautifully clear and eminently readable, it will be noticed."–Geoffrey Brennan, University of North Carolina, Chapel Hill

"Brennan's book is provocative in the best sense of the word–a fresh and challenging approach to important matters in political theory and political ethics. It is also a remarkably accessible book that manages to capture nuances and subtleties without unnecessary complication or jargon. In these respects, The Ethics of Voting is a model of how political philosophy should proceed."–Richard Dagger, University of Richmond

(*The one exception to this rule occurs in the chapter called "Arguments for a Duty to Vote". I needed to do some mathematics there. )
