A somewhat dated book explaining the construction of a political map from a few years ago. It is well written but flawed because it's many predictions turned out wrong. Yet there are many passages that relate to both old and future elections.
The author, Hugh Hewitt, makes a very good case for disregardling third political parties as irrelevant. He believes the only way to make a real impact upon our national politics is to make your views (preferably Conservative) within the Democratic or Republican party - and then throwing your entire support to the party of your choice.
Mr. Hewitt is persuasive.
A good book.
