After observing the strains of intense partisanship and divided government, many Americans are wondering what logic, if any, can be found in politics. The new Sixth Edition of The Logic of American Politics reaffirms this best-seller's place as the most accessible "smart" book on the market. Consistently praised for its engaging narrative, the book hooks students with great storytelling while arming them with a "toolkit" of institutional design concepts-command, veto, agenda control, voting rules, delegation.
