US politics today not only introduces the defining features of contemporary American politics but also considers the strengths and weaknesses of a system that is now under serious strain. The book is ideal for students, teaching staff and the general reader. It outlines the ways in which the Constitution shapes the politics of today, surveys the role of the presidency, Congress and the federal courts, and examines processes of political participation through elections, organized interests and parties. It pays particular attention to Barack Obama and Donald Trump’s turbulent years in office and the ways in which recent decades have reshaped the US political landscape. US politics today also places the US in a comparative context and considers key theoretical perspectives. In sum, the book not only provides an indispensable introduction to contemporary American politics but establishes a basis for informed commentary and further study. — .
