'Finally, a thinking person's guide to the damage done by the Trump presidency. Campbell makes a convincing case, grounded in high-quality evidence and innovative thinking about institutional change, that Trump undermined virtually all the key institutions of American democracy in his four norm-smashing years in the White House.' Jacob S. Hacker, Yale University
'Many books have been written on the Trump presidency. Some applaud this unusual president many more decry his governance and personal style. John Campbell's thoughtful book, 'Institutions Under Siege,' is the first to consider the implications of Donald Trump from the perspective of institutional change. Campbell has written several excellent monographs on institutional evolution and change. In this incisive book he examines how the Trump presidency has shaped and reshaped American political institutions. In so doing Campbell offers both a fascinating account of what Trump did, and could not do, to America's political institutions and deepens our understanding of the mechanisms of institutional change itself.'
