The Imperiled Presidency: Presidential Leadership in the 21st Century calls for a dramatic re-evaluation of the American president's role within the separation of powers system. In contrast with claims by academics, pundits, media, and members of Congress, Cal Mackenzie offers the contrarian argument that the real constitutional crisis in contemporary American politics is t the centralization and accumulation of power in the presidency (the imperial presidency argument), but rather that effective governance is imperiled by the diminished role of the presidency. The product of more than three years of research and writing and nearly four decades of the author's teaching and writing about the American presidency, The Imperiled Presidency is the first book-length treatment of the weaknesses of the modern presidency, written to be accessible to undergraduates and interested citizens alike.
