Query: Clear and concise introduction to American Political and Institutional Theory

The Contours of American Politics proved itself to be a very accessible and clear in terms of guiding the reader through the primary characteristics of American Politics. Taking time to sketch the historical context which continues to frame contemporary American Politics, Roper lucidly outlines the broader political themes and ideals - from the early contested formation of the Union right through to the emergence of the civil rights movement and beyond - which have been so instrumental in shaping the politics of modern America.Personally, should Roper produce a 2nd Ed., then I'd welcome a section or two on the process of political centralization among the two prevailing political ideologies and, perhaps, a section outlining the significance of US-Israeli political relations in contemporary American Political Discourse.
